 * Prefer implementing functionality in existing files unless it is a new logical component. Avoid creating many small files.
 * Avoid using functions that panic like `unwrap()`, instead use mechanisms like `?` to propagate errors.
 * Be careful with operations like indexing which may panic if the indexes are out of bounds.
-* Never silently discard errors with `let _ =` on fallible operations. Always handle errors appropriately:
-  - Propagate errors with `?` when the calling function should handle them
-  - Use `.log_err()` or similar when you need to ignore errors but want visibility
-  - Use explicit error handling with `match` or `if let Err(...)` when you need custom logic
-  - Example: avoid `let _ = client.request(...).await?;` - use `client.request(...).await?;` instead
-* When implementing async operations that may fail, ensure errors propagate to the UI layer so users get meaningful feedback.
 * Never create files with `mod.rs` paths - prefer `src/some_module.rs` instead of `src/some_module/mod.rs`.

-//! Link folding support for channel notes.
-//!
-//! This module provides functionality to automatically fold markdown links in channel notes,
-//! displaying only the link text with an underline decoration. When the cursor is positioned
-//! inside a link, the crease is temporarily removed to show the full markdown syntax.
-//!
-//! Example:
-//! - When rendered: [Example](https://example.com) becomes "Example" with underline
-//! - When cursor is inside: Full markdown syntax is shown
-//!
-//! The main components are:
-//! - `parse_markdown_links`: Extracts markdown links from text
-//! - `create_link_creases`: Creates visual creases for links
-//! - `LinkFoldingManager`: Manages dynamic showing/hiding of link creases based on cursor position
