+# Telegram Desktop API Usage
+
+## API Schema
+
+The API definitions are described using [TL Language]\(https:/core.telegram.org/mtproto/TL) in two main schema files:
+
+1.  **`Telegram/SourceFiles/mtproto/scheme/mtproto.tl`**
+    *   Defines the core MTProto protocol types and methods used for basic communication, encryption, authorization, service messages, etc.
+    *   Some fundamental types and methods from this schema (like basic types, RPC calls, containers) are often implemented directly in the C++ MTProto core (`SourceFiles/mtproto/`) and may be skipped during the C++ code generation phase.
+    *   Other parts of `mtproto.tl` might still be processed by the code generator.
+
+2.  **`Telegram/SourceFiles/mtproto/scheme/api.tl`**
+    *   Defines the higher-level Telegram API layer, including all the methods and types related to chat functionality, user profiles, messages, channels, stickers, etc.
+    *   This is the primary schema used when making functional API requests within the application.
+
+Both files use the same TL syntax to describe API methods (functions) and types (constructors).
+
+## Code Generation
+
+A custom code generation tool processes `api.tl` (and parts of `mtproto.tl`) to create corresponding C++ classes and types. These generated headers are typically included via the Precompiled Header (PCH) for the main `Telegram` project.
+
+Generated types often follow the pattern `MTP[Type]` (e.g., `MTPUser`, `MTPMessage`) and methods correspond to functions within the `MTP` namespace or related classes (e.g., `MTPmessages_SendMessage`).
+
+## Making API Requests
+
+API requests are made using a standard pattern involving the `api()` object (providing access to the `MTP::Instance`), the generated `MTP...` request object, callback handlers for success (`.done()`) and failure (`.fail()`), and the `.send()` method.
+
+Here's the general structure:
+
+```cpp
+// Include necessary headers if not already in PCH
+
+// Obtain the API instance (usually via api() or MTP::Instance::Get())
+api().request(MTPnamespace_MethodName(
+    // Constructor arguments based on the api.tl definition for the method
+    MTP_flags(flags_value),      // Use MTP_flags if the method has flags
+    MTP_inputPeer(peer),         // Use MTP_... types for parameters
+    MTP_string(messageText),
+    MTP_long(randomId),
+    // ... other arguments matching the TL definition
+    MTP_vector<MTPMessageEntity>() // Example for a vector argument
+)).done([=]\(const MTPResponseType &result) {
+    // Handle the successful response (result).
+    // 'result' will be of the C++ type corresponding to the TL type
+    // specified after the '=' in the api.tl method definition.
+    // How to access data depends on whether the TL type has one or multiple constructors:
+
+    // 1. Multiple Constructors (e.g., User = User | UserEmpty):
+    //    Use .match() with lambdas for each constructor:
+    result.match([&]\(const MTPDuser &data) {
+        /* use data.vfirst_name().v, etc. */
+    }, [&]\(const MTPDuserEmpty &data) {
+        /* handle empty user */
+    });
+
+    //    Alternatively, check the type explicitly and use the constructor getter:
+    if (result.type() == mtpc_user) {
+        const auto &data = result.c_user(); // Asserts if type is not mtpc_user!
+        // use data.vfirst_name().v
+    } else if (result.type() == mtpc_userEmpty) {
+        const auto &data = result.c_userEmpty();
+        // handle empty user
+    }
+
+    // 2. Single Constructor (e.g., Messages = messages { msgs: vector<Message> }):
+    //    Use .match() with a single lambda:
+    result.match([&]\(const MTPDmessages &data) { /* use data.vmessages().v */ });
+
+    //    Or check the type explicitly and use the constructor getter:
+    if (result.type() == mtpc_messages) {
+        const auto &data = result.c_messages(); // Asserts if type is not mtpc_messages!
+        // use data.vmessages().v
+    }
+
+    //    Or use the shortcut .data() for single-constructor types:
+    const auto &data = result.data(); // Only works for single-constructor types!
+    // use data.vmessages().v
+
+}).fail([=]\(const MTP::Error &error) {
+    // Handle the API error (error).
+    // 'error' is an MTP::Error object containing the error code (error.type())
+    // and description (error.description()). Check for specific error strings.
+    if (error.type() == u"FLOOD_WAIT_X"_q) {
+        // Handle flood wait
+    } else {
+        Ui::show(Box<InformBox>(Lang::Hard::ServerError())); // Example generic error handling
+    }
+}).handleFloodErrors().send(); // handleFloodErrors() is common, then send()
+```
+
+**Key Points:**
+
+*   Always refer to `Telegram/SourceFiles/mtproto/scheme/api.tl` for the correct method names, parameters (names and types), and response types.
+*   Use the generated `MTP...` types/classes for request parameters (e.g., `MTP_int`, `MTP_string`, `MTP_bool`, `MTP_vector`, `MTPInputUser`, etc.) and response handling.
+*   The `.done()` lambda receives the specific C++ `MTP...` type corresponding to the TL return type.
+    *   For types with **multiple constructors** (e.g., `User = User | UserEmpty`), use `result.match([&]\(const MTPDuser &d){ ... }, [&]\(const MTPDuserEmpty &d){ ... })` to handle each case, or check `result.type() == mtpc_user` / `mtpc_userEmpty` and call the specific `result.c_user()` / `result.c_userEmpty()` getter (which asserts on type mismatch).
+    *   For types with a **single constructor** (e.g., `Messages = messages{...}`), you can use `result.match([&]\(const MTPDmessages &d){ ... })` with one lambda, or check `type()` and call `c_messages()`, or use the shortcut `result.data()` to access the fields directly.
+*   The `.fail()` lambda receives an `MTP::Error` object. Check `error.type()` against known error strings (often defined as constants or using `u"..."_q` literals).
+*   Directly construct the `MTPnamespace_MethodName(...)` object inside `request()`.
+*   Include `.handleFloodErrors()` before `.send()` for standard flood wait handling.

+# Telegram Desktop Localization
+
+## Coding Style Note
+
+**Use `auto`:** In the actual codebase, variable types are almost always deduced using `auto` (or `const auto`, `const auto &`) rather than being written out explicitly. Examples in this guide may use explicit types for clarity, but prefer `auto` in practice.
+
+```cpp
+// Prefer this:
+auto currentTitle = tr::lng_settings_title(tr::now);
+auto nameProducer = GetNameProducer(); // Returns rpl::producer<...>
+
+// Instead of this:
+QString currentTitle = tr::lng_settings_title(tr::now);
+rpl::producer<QString> nameProducer = GetNameProducer();
+```
+
+## String Resource File
+
+Base user-facing English strings are defined in the `lang.strings` file:
+
+`Telegram/Resources/langs/lang.strings`
+
+This file uses a key-value format with named placeholders:
+
+```
+"lng_settings_title" = "Settings";
+"lng_confirm_delete_item" = "Are you sure you want to delete {item_name}?";
+"lng_files_selected" = "{count} files selected"; // Simple count example (see Pluralization)
+```
+
+Placeholders are enclosed in curly braces, e.g., `{name}`, `{user}`. A special placeholder `{count}` is used for pluralization rules.
+
+### Pluralization
+
+For keys that depend on a number (using the `{count}` placeholder), English typically requires two forms: singular and plural. These are defined in `lang.strings` using `#one` and `#other` suffixes:
+
+```
+"lng_files_selected#one" = "{count} file selected";
+"lng_files_selected#other" = "{count} files selected";
+```
+
+While only `#one` and `#other` are defined in the base `lang.strings`, the code generation process creates C++ accessors for all six CLDR plural categories (`#zero`, `#one`, `#two`, `#few`, `#many`, `#other`) to support languages with more complex pluralization rules.
+
+## Translation Process
+
+While `lang.strings` provides the base English text and the keys, the actual translations are managed via Telegram's translations platform (translations.telegram.org) and loaded dynamically at runtime from the API. The keys from `lang.strings` (including the `#one`/`#other` variants) are used on the platform.
+
+## Code Generation
+
+A code generation tool processes `lang.strings` to create C++ structures and accessors within the `tr` namespace. These allow type-safe access to strings and handling of placeholders and pluralization. Generated keys typically follow the pattern `tr::lng_key_name`.
+
+## String Usage in Code
+
+Strings are accessed in C++ code using the generated objects within the `tr::` namespace. There are two main ways to use them: reactively (returning an `rpl::producer`) or immediately (returning the current value).
+
+### 1. Reactive Usage (rpl::producer)
+
+Calling a generated string function directly returns a reactive producer, typically `rpl::producer<QString>`. This producer automatically updates its value whenever the application language changes.
+
+```cpp
+// Key: "settings_title" = "Settings";
+auto titleProducer = tr::lng_settings_title(); // Type: rpl::producer<QString>
+
+// Key: "confirm_delete_item" = "Are you sure you want to delete {item_name}?";
+auto itemNameProducer = /* ... */; // Type: rpl::producer<QString>
+auto confirmationProducer = tr::lng_confirm_delete_item( // Type: rpl::producer<QString>
+    tr::now, // NOTE: tr::now is NOT passed here for reactive result
+    lt_item_name,
+    std::move(itemNameProducer)); // Placeholder producers should be moved
+```
+
+### 2. Immediate Usage (Current Value)
+
+Passing `tr::now` as the first argument retrieves the string's current value in the active language (typically as a `QString`).
+
+```cpp
+// Key: "settings_title" = "Settings";
+auto currentTitle = tr::lng_settings_title(tr::now); // Type: QString
+
+// Key: "confirm_delete_item" = "Are you sure you want to delete {item_name}?";
+const auto currentItemName = QString("My Document"); // Type: QString
+auto currentConfirmation = tr::lng_confirm_delete_item( // Type: QString
+    tr::now, // Pass tr::now for immediate value
+    lt_item_name, currentItemName); // Placeholder value is a direct QString (or convertible)
+```
+
+### 3. Placeholders (`{tag}`)
+
+Placeholders like `{item_name}` are replaced by providing arguments after `tr::now` (for immediate) or as the initial arguments (for reactive). A corresponding `lt_tag_name` constant is passed before the value.
+
+*   **Immediate:** Pass the direct value (e.g., `QString`, `int`).
+*   **Reactive:** Pass an `rpl::producer` of the corresponding type (e.g., `rpl::producer<QString>`). Remember to `std::move` the producer or use `rpl::duplicate` if you need to reuse the original producer afterwards.
+
+### 4. Pluralization (`{count}`)
+
+Keys using `{count}` require a numeric value for the `lt_count` placeholder. The correct plural form (`#zero`, `#one`, ..., `#other`) is automatically selected based on this value and the current language rules.
+
+*   **Immediate (`tr::now`):** Pass a `float64` or `int` (which is auto-converted to `float64`).
+    ```cpp
+    int count = 1;
+    auto filesText = tr::lng_files_selected(tr::now, lt_count, count); // Type: QString
+    count = 5;
+    filesText = tr::lng_files_selected(tr::now, lt_count, count); // Uses "files_selected#other"
+    ```
+
+*   **Reactive:** Pass an `rpl::producer<float64>`. Use the `tr::to_count()` helper to convert an `rpl::producer<int>` or wrap a single value.
+    ```cpp
+    // From an existing int producer:
+    auto countProducer = /* ... */; // Type: rpl::producer<int>
+    auto filesTextProducer = tr::lng_files_selected( // Type: rpl::producer<QString>
+        lt_count,
+        countProducer | tr::to_count()); // Use tr::to_count() for conversion
+
+    // From a single int value wrapped reactively:
+    int currentCount = 5;
+    auto filesTextProducerSingle = tr::lng_files_selected( // Type: rpl::producer<QString>
+        lt_count,
+        rpl::single(currentCount) | tr::to_count());
+        // Alternative for single values (less common): rpl::single(currentCount * 1.)
+    ```
+
+### 5. Custom Projectors
+
+An optional final argument can be a projector function (like `Ui::Text::Upper` or `Ui::Text::WithEntities`) to transform the output.
+
+*   If the projector returns `OutputType`, the string function returns `OutputType` (immediate) or `rpl::producer<OutputType>` (reactive).
+*   Placeholder values must match the projector's *input* requirements. For `Ui::Text::WithEntities`, placeholders expect `TextWithEntities` (immediate) or `rpl::producer<TextWithEntities>` (reactive).
+
+```cpp
+// Immediate with Ui::Text::WithEntities projector
+// Key: "user_posted_photo" = "{user} posted a photo";
+const auto userName = TextWithEntities{ /* ... */ }; // Type: TextWithEntities
+auto message = tr::lng_user_posted_photo( // Type: TextWithEntities
+    tr::now,
+    lt_user,
+    userName, // Must be TextWithEntities
+    Ui::Text::WithEntities); // Projector
+
+// Reactive with Ui::Text::WithEntities projector
+auto userNameProducer = /* ... */; // Type: rpl::producer<TextWithEntities>
+auto messageProducer = tr::lng_user_posted_photo( // Type: rpl::producer<TextWithEntities>
+    lt_user,
+    std::move(userNameProducer), // Move placeholder producers
+    Ui::Text::WithEntities); // Projector
+```
+
+## Key Summary
+
+*   Keys are defined in `Resources/langs/lang.strings` using `{tag}` placeholders.
+*   Plural keys use `{count}` and have `#one`/`#other` variants in `lang.strings`.
+*   Access keys via `tr::lng_key_name(...)` in C++.
+*   Call with `tr::now` as the first argument for the immediate `QString` (or projected type).
+*   Call without `tr::now` for the reactive `rpl::producer<QString>` (or projected type).
+*   Provide placeholder values (`lt_tag_name, value`) matching the usage (direct value for immediate, `rpl::producer` for reactive). Producers should typically be moved via `std::move`.
+*   For `{count}`:
+    *   Immediate: Pass `int` or `float64`.
+    *   Reactive: Pass `rpl::producer<float64>`, typically by converting an `int` producer using `| tr::to_count()`.
+*   Optional projector function as the last argument modifies the output type and required placeholder types.
+*   Actual translations are loaded at runtime from the API.

+# RPL (Reactive Programming Library) Guide
+
+## Coding Style Note
+
+**Use `auto`:** In the actual codebase, variable types are almost always deduced using `auto` (or `const auto`, `const auto &`) rather than being written out explicitly. Examples in this guide may use explicit types for clarity, but prefer `auto` in practice.
+
+```cpp
+// Prefer this:
+auto intProducer = rpl::single(123);
+const auto &lifetime = existingLifetime;
+
+// Instead of this:
+rpl::producer<int> intProducer = rpl::single(123);
+const rpl::lifetime &lifetime = existingLifetime;
+
+// Sometimes needed if deduction is ambiguous or needs help:
+auto user = std::make_shared<UserData>();
+auto data = QByteArray::fromHex("...");
+```
+
+## Introduction
+
+RPL is the reactive programming library used in this project, residing in the `rpl::` namespace. It allows handling asynchronous streams of data over time.
+
+The core concept is the `rpl::producer`, which represents a stream of values that can be generated over a certain lifetime.
+
+## Producers: `rpl::producer<Type, Error = no_error>`
+
+The fundamental building block is `rpl::producer<Type, Error>`. It produces values of `Type` and can optionally signal an error of type `Error`. By default, `Error` is `rpl::no_error`, indicating that the producer does not explicitly handle error signaling through this mechanism.
+
+```cpp
+// A producer that emits integers.
+auto intProducer = /* ... */; // Type: rpl::producer<int>
+
+// A producer that emits strings and can potentially emit a CustomError.
+auto stringProducerWithError = /* ... */; // Type: rpl::producer<QString, CustomError>
+```
+
+Producers are typically lazy; they don't start emitting values until someone subscribes to them.
+
+## Lifetime Management: `rpl::lifetime`
+
+Reactive pipelines have a limited duration, managed by `rpl::lifetime`. An `rpl::lifetime` object essentially holds a collection of cleanup callbacks. When the lifetime ends (either explicitly destroyed or goes out of scope), these callbacks are executed, tearing down the associated pipeline and freeing resources.
+
+```cpp
+rpl::lifetime myLifetime;
+// ... later ...
+// myLifetime is destroyed, cleanup happens.
+
+// Or, pass a lifetime instance to manage a pipeline's duration.
+rpl::lifetime &parentLifetime = /* ... get lifetime from context ... */;
+```
+
+## Starting a Pipeline: `rpl::start_...`
+
+To consume values from a producer, you start a pipeline using one of the `rpl::start_...` methods. These methods subscribe to the producer and execute callbacks for the events they handle.
+
+The most common method is `rpl::start_with_next`:
+
+```cpp
+auto counter = /* ... */; // Type: rpl::producer<int>
+rpl::lifetime lifetime;
+
+// Counter is consumed here, use std::move if it's an l-value.
+std::move(
+    counter
+) | rpl::start_with_next([=]\(int nextValue) {
+    // Process the next integer value emitted by the producer.
+    qDebug() << "Received: " << nextValue;
+}, lifetime); // Pass the lifetime to manage the subscription.
+// Note: `counter` is now in a moved-from state and likely invalid.
+
+// If you need to start the same producer multiple times, duplicate it:
+// rpl::duplicate(counter) | rpl::start_with_next(...);
+
+// If you DON'T pass a lifetime to a start_... method:
+auto counter2 = /* ... */; // Type: rpl::producer<int>
+rpl::lifetime subscriptionLifetime = std::move(
+    counter2
+) | rpl::start_with_next([=]\(int nextValue) { /* ... */ });
+// The returned lifetime MUST be stored. If it's discarded immediately,
+// the subscription stops instantly.
+// `counter2` is also moved-from here.
+```
+
+Other variants allow handling errors (`_error`) and completion (`_done`):
+
+```cpp
+auto dataStream = /* ... */; // Type: rpl::producer<QString, Error>
+rpl::lifetime lifetime;
+
+// Assuming dataStream might be used again, we duplicate it for the first start.
+// If it's the only use, std::move(dataStream) would be preferred.
+rpl::duplicate(
+    dataStream
+) | rpl::start_with_error([=]\(Error &&error) {
+    // Handle the error signaled by the producer.
+    qDebug() << "Error: " << error.text();
+}, lifetime);
+
+// Using dataStream again, perhaps duplicated again or moved if last use.
+rpl::duplicate(
+    dataStream
+) | rpl::start_with_done([=] {
+    // Execute when the producer signals it's finished emitting values.
+    qDebug() << "Stream finished.";
+}, lifetime);
+
+// Last use of dataStream, so we move it.
+std::move(
+    dataStream
+) | rpl::start_with_next_error_done(
+    [=]\(QString &&value) { /* handle next value */ },
+    [=]\(Error &&error) { /* handle error */ },
+    [=] { /* handle done */ },
+    lifetime);
+```
+
+## Transforming Producers
+
+RPL provides functions to create new producers by transforming existing ones:
+
+*   `rpl::map`: Transforms each value emitted by a producer.
+    ```cpp
+    auto ints = /* ... */; // Type: rpl::producer<int>
+    // The pipe operator often handles the move implicitly for chained transformations.
+    auto strings = std::move(
+        ints // Explicit move is safer
+    ) | rpl::map([](int value) {
+        return QString::number(value * 2);
+    }); // Emits strings like "0", "2", "4", ...
+    ```
+
+*   `rpl::filter`: Emits only the values from a producer that satisfy a condition.
+    ```cpp
+    auto ints = /* ... */; // Type: rpl::producer<int>
+    auto evenInts = std::move(
+        ints // Explicit move is safer
+    ) | rpl::filter([](int value) {
+        return (value % 2 == 0);
+    }); // Emits only even numbers.
+    ```
+
+## Combining Producers
+
+You can combine multiple producers into one:
+
+*   `rpl::combine`: Combines the latest values from multiple producers whenever *any* of them emits a new value. Requires all producers to have emitted at least one value initially.
+    While it produces a `std::tuple`, subsequent operators like `map`, `filter`, and `start_with_next` can automatically unpack this tuple into separate lambda arguments.
+    ```cpp
+    auto countProducer = rpl::single(1); // Type: rpl::producer<int>
+    auto textProducer = rpl::single(u"hello"_q); // Type: rpl::producer<QString>
+    rpl::lifetime lifetime;
+
+    // rpl::combine takes producers by const-ref internally and duplicates,
+    // so move/duplicate is usually not strictly needed here unless you
+    // want to signal intent or manage the lifetime of p1/p2 explicitly.
+    auto combined = rpl::combine(
+        countProducer, // or rpl::duplicate(countProducer)
+        textProducer   // or rpl::duplicate(textProducer)
+    );
+
+    // Starting the combined producer consumes it.
+    // The lambda receives unpacked arguments, not the tuple itself.
+    std::move(
+        combined
+    ) | rpl::start_with_next([=]\(int count, const QString &text) {
+        // No need for std::get<0>(latest), etc.
+        qDebug() << "Combined: Count=" << count << ", Text=" << text;
+    }, lifetime);
+
+    // This also works with map, filter, etc.
+    std::move(
+        combined
+    ) | rpl::filter([=]\(int count, const QString &text) {
+        return count > 0 && !text.isEmpty();
+    }) | rpl::map([=]\(int count, const QString &text) {
+        return text.repeated(count);
+    }) | rpl::start_with_next([=]\(const QString &result) {
+        qDebug() << "Mapped & Filtered: " << result;
+    }, lifetime);
+    ```
+
+*   `rpl::merge`: Merges the output of multiple producers of the *same type* into a single producer. It emits a value whenever *any* of the source producers emits a value.
+    ```cpp
+    auto sourceA = /* ... */; // Type: rpl::producer<QString>
+    auto sourceB = /* ... */; // Type: rpl::producer<QString>
+
+    // rpl::merge also duplicates internally.
+    auto merged = rpl::merge(sourceA, sourceB);
+
+    // Starting the merged producer consumes it.
+    std::move(
+        merged
+    ) | rpl::start_with_next([=]\(QString &&value) {
+        // Receives values from either sourceA or sourceB as they arrive.
+        qDebug() << "Merged value: " << value;
+    }, lifetime);
+    ```
+
+## Key Concepts Summary
+
+*   Use `rpl::producer<Type, Error>` to represent streams of values.
+*   Manage subscription duration using `rpl::lifetime`.
+*   Pass `rpl::lifetime` to `rpl::start_...` methods.
+*   If `rpl::lifetime` is not passed, **store the returned lifetime** to keep the subscription active.
+*   Use operators like `| rpl::map`, `| rpl::filter` to transform streams.
+*   Use `rpl::combine` or `rpl::merge` to combine streams.
+*   When starting a chain (`std::move(producer) | rpl::map(...)`), explicitly move the initial producer.
+*   These functions typically duplicate their input producers internally.
+*   Starting a pipeline consumes the producer; use `

+# Telegram Desktop UI Styling
+
+## Style Definition Files
+
+UI element styles (colors, fonts, paddings, margins, icons, etc.) are defined in `.style` files using a custom syntax. These files are located alongside the C++ source files they correspond to within specific UI component directories (e.g., `Telegram/SourceFiles/ui/chat/chat.style`).
+
+Definitions from other `.style` files can be included using the `using` directive at the top of the file:
+```style
+using "ui/basic.style";
+using "ui/widgets/widgets.style";
+```
+
+The central definition of named colors happens in `Telegram/SourceFiles/ui/colors.palette`. This file allows for theme generation and loading colors from various sources.
+
+### Syntax Overview
+
+1.  **Built-in Types:** The syntax recognizes several base types inferred from the value assigned:
+    *   `int`: Integer numbers (e.g., `lineHeight: 20;`)
+    *   `bool`: Boolean values (e.g., `useShadow: true;`)
+    *   `pixels`: Pixel values, ending with `px` (e.g., `borderWidth: 1px;`). Generated as `int` in C++.
+    *   `color`: Named colors defined in `colors.palette` (e.g., `background: windowBg;`)
+    *   `icon`: Defined inline using a specific syntax (see below). Generates `style::icon`.
+    *   `margins`: Four pixel values for margins or padding. Requires `margins(top, right, bottom, left)` syntax (e.g., `margin: margins(10px, 5px, 10px, 5px);` or `padding: margins(8px, 8px, 8px, 8px);`). Generates `style::margins` (an alias for `QMargins`).
+    *   `size`: Two pixel values for width and height (e.g., `iconSize: size(16px, 16px);`). Generates `style::size`.
+    *   `point`: Two pixel values for x and y coordinates (e.g., `textPos: point(5px, 2px);`). Generates `style::point`.
+    *   `align`: Alignment keywords (e.g., `textAlign: align(center);` or `iconAlign: align(left);`). Generates `style::align`.
+    *   `font`: Font definitions (e.g., `font: font(14px semibold);`). Generates `style::font`.
+    *   `double`: Floating point numbers (e.g., `disabledOpacity: 0.5;`)
+
+    *Note on Borders:* Borders are typically defined using multiple fields like `border: pixels;` (for width) and `borderFg: color;` (for color), rather than a single CSS-like property.
+
+2.  **Structure Definition:** You can define complex data structures directly within the `.style` file:
+    ```style
+    MyButtonStyle { // Defines a structure named 'MyButtonStyle'
+      textPadding: margins; // Field 'textPadding' expects margins type
+      icon: icon;         // Field 'icon' of type icon
+      height: pixels;     // Field 'height' of type pixels
+    }
+    ```
+    This generates a `struct MyButtonStyle { ... };` inside the `namespace style`. Fields will have corresponding C++ types (`style::margins`, `style::icon`, `int`).
+
+3.  **Variable Definition & Inheritance:** Variables are defined using `name: value;` or `groupName { ... }`. They can be of built-in types or custom structures. Structures can be initialized inline or inherit from existing variables.
+
+    **Icon Definition Syntax:** Icons are defined inline using the `icon{...}` syntax. The generator probes for `.svg` files or `.png` files (including `@2x`, `@3x` variants) based on the provided path stem.
+    ```style
+    // Single-part icon definition:
+    myIconSearch: icon{{ "gui/icons/search", iconColor }};
+    // Multi-part icon definition (layers drawn bottom-up):
+    myComplexIcon: icon{
+      { "gui/icons/background", iconBgColor },
+      { "gui/icons/foreground", iconFgColor }
+    };
+    // Icon with path modifiers (PNG only for flips, SVG only for size):
+    myFlippedIcon: icon{{ "gui/icons/arrow-flip_horizontal", arrowColor }};
+    myResizedIcon: icon{{ "gui/icons/logo-128x128", logoColor }}; // Forces 128x128 for SVG
+    ```
+
+    **Other Variable Examples:**
+    ```style
+    // Simple variables
+    buttonHeight: 30px;
+    activeButtonColor: buttonBgActive; // Named color from colors.palette
+
+    // Variable of a custom structure type, initialized inline
+    defaultButton: MyButtonStyle {
+      textPadding: margins(10px, 15px, 10px, 15px); // Use margins(...) syntax
+      icon: myIconSearch; // Assign the previously defined icon variable
+      height: buttonHeight; // Reference another variable
+    }
+
+    // Another variable inheriting from 'defaultButton' and overriding/adding fields
+    primaryButton: MyButtonStyle(defaultButton) {
+      icon: myComplexIcon; // Override icon with the multi-part one
+      backgroundColor: activeButtonColor; // Add a field not in MyButtonStyle definition
+    }
+
+    // Style group (often used for specific UI elements)
+    chatInput { // Example using separate border properties and explicit padding
+      border: 1px;                          // Border width
+      borderFg: defaultInputFieldBorder;    // Border color (named color)
+      padding: margins(5px, 10px, 5px, 10px); // Use margins(...) syntax for padding field
+      backgroundColor: defaultChatBg;       // Background color
+    }
+    ```
+
+## Code Generation
+
+A code generation tool processes these `.style` files and `colors.palette` to create C++ objects.
+- The `using` directives resolve dependencies between `.style` files.
+- Custom structure definitions (like `MyButtonStyle`) generate corresponding `struct MyButtonStyle { ... };` within the `namespace style`.
+- Style variables/groups (like `defaultButton`, `primaryButton`, `chatInput`) are generated as objects/structs within the `st` namespace (e.g., `st::defaultButton`, `st::primaryButton`, `st::chatInput`). These generated structs contain members corresponding to the fields defined in the `.style` file.
+- Color objects are generated into the `st` namespace as well, based on their names in `colors.palette` (e.g., `st::windowBg`, `st::buttonBgActive`).
+- The generated header files for styles are placed in the `Telegram/SourceFiles/styles/` directory with a `style_` prefix (e.g., `styles/style_widgets.h` for `ui/widgets/widgets.style`). You include them like `#include "styles/style_widgets.h"`.
+
+Generated C++ types correspond to the `.style` types: `style::color`, `style::font`, `style::margins` (used for both `margin:` and `padding:` fields), `style::icon`, `style::size`, `style::point`, `style::align`, and `int` or `bool` for simple types.
+
+## Style Usage in Code
+
+Styles are applied in C++ code by referencing the generated `st::...` objects and their members.
+
+```cpp
+// Example: Including the generated style header
+#include "styles/style_widgets.h" // For styles defined in ui/widgets/widgets.style
+
+// ... inside some UI class code ...
+
+// Accessing members of a generated style struct
+int height = st::primaryButton.height; // Accessing the 'height' field (pixels -> int)
+const style::icon &icon = st::primaryButton.icon; // Accessing the 'icon' field (st::myComplexIcon)
+style::margins padding = st::primaryButton.textPadding; // Accessing 'textPadding'
+style::color bgColor = st::primaryButton.backgroundColor; // Accessing the color (st::activeButtonColor)
+
+// Applying styles (conceptual examples)
+myButton->setIcon(st::primaryButton.icon);
+myButton->setHeight(st::primaryButton.height);
+myButton->setPadding(st::primaryButton.textPadding);
+myButton->setBackgroundColor(st::primaryButton.backgroundColor);
+
+// Using styles directly in painting
+void MyWidget::paintEvent(QPaintEvent *e) {
+    Painter p(this);
+    p.fillRect(rect(), st::chatInput.backgroundColor); // Use color from chatInput style
+
+    // Border painting requires width and color
+    int borderWidth = st::chatInput.border; // Access border width (pixels -> int)
+    style::color borderColor = st::chatInput.borderFg; // Access border color
+    if (borderWidth > 0) {
+        p.setPen(QPen(borderColor, borderWidth));
+        // Adjust rect for pen width if needed before drawing
+        p.drawRect(rect().adjusted(borderWidth / 2, borderWidth / 2, -borderWidth / 2, -borderWidth / 2));
+    }
+
+    // Access padding (style::margins)
+    style::margins inputPadding = st::chatInput.padding;
+    // ... use inputPadding.top(), inputPadding.left() etc. for content layout ...
+}
+```
+
+**Key Points:**
+
+*   Styles are defined in `.style` files next to their corresponding C++ source files.
+*   `using "path/to/other.style";` includes definitions from other style files.
+*   Named colors are defined centrally in `ui/colors.palette`.
+*   `.style` syntax supports built-in types (like `pixels`, `color`, `margins`, `point`, `size`, `align`, `font`, `double`), custom structure definitions (`Name { field: type; ... }`), variable definitions (`name: value;`), and inheritance (`child: Name(parent) { ... }`).
+*   Values must match the expected type (e.g., fields declared as `margins` type, like `margin:` or `padding:`, require `margins(...)` syntax). Borders are typically set via separate `border: pixels;` and `borderFg: color;` fields.
+*   Icons are defined inline using `name: icon{{ "path_stem", color }};` or `name: icon{ { "path1", c1 }, ... };` syntax, with optional path modifiers.
+*   Code generation creates `struct` definitions in the `style` namespace for custom types and objects/structs in the `st` namespace for defined variables/groups.
+*   Generated headers are in `styles/` with a `style_` prefix and must be included.
+*   Access style properties via the generated `st::` objects (e.g., `st::primaryButton.height`, `st::chatInput.backgroundColor`).
