- Introduce `LayoutSnapshot` to capture the geometry of UI panels each render cycle.
- Store the latest layout snapshot in `ChatApp` for mouse region lookup.
- Implement mouse click and scroll handling across panels (file tree, thinking, actions, code, model info, chat, input, etc.).
- Add utility functions for region detection, cursor placement from mouse position, and scrolling logic.
- Update UI rendering to populate the layout snapshot with panel rectangles.
- New test suite in `crates/owlen-tui/tests` covering generation orchestration, message variant round‑trip, and background worker status updates.
- Extend `model_picker` to filter models by matching keywords against capabilities as well as provider names.
- Update `state_tests` to assert that suggestion lists are non‑empty instead of checking prefix matches.
- Re‑export `background_worker` from `app::mod.rs` for external consumption.
- Add `MessageState` trait defining UI reaction callbacks for generation lifecycle, model updates, provider status, resize, and tick events.
- Implement `App::handle_message` to route `AppMessage` variants to the provided `MessageState` and determine exit condition.
- Add `handler.rs` module with the trait and dispatch logic; re-export `MessageState` in `app/mod.rs`.
- Extend `ActiveGeneration` with a public `request_id` getter and clean up dead code annotations.
- Implement empty `MessageState` for `ChatApp` to integrate UI handling.
- Add `log` crate dependency for warning messages.
Added `widgets::model_picker` containing the full model picker rendering logic and moved related helper functions there. Updated `ui.rs` to use `render_model_picker` and removed the now‑duplicate model selector implementation. This cleanly separates UI concerns and improves code reuse.
Introduce a `worker` module with `background_worker` that periodically refreshes provider health and emits status updates via the app's message channel. Add `spawn_background_worker` method to `App` for launching the worker as a Tokio task.
Introduce `App` with provider manager, unbounded message channel, and active generation tracking.
Add `AppMessage` enum covering UI events, generation lifecycle (start, chunk, complete, error), model refresh, and provider status updates.
Implement `start_generation` to spawn asynchronous generation tasks, stream results, handle errors, and abort any previous generation.
Expose the new module via `pub mod app` in the crate root.
- Introduce `MIN_MESSAGE_CARD_WIDTH` and use it to switch to compact card layout when terminal width is limited.
- Implement `clip_line_to_width` to truncate UI lines based on available width, preventing overflow in model selector and headers.
- Adjust viewport and card width calculations to respect inner area constraints and handle compact cards.
- Update resize handling and rendering logic to use the new width calculations and clipping functionality.

- Extend UI hint strings across panels to include the new focus shortcuts.
- Refactor highlight style handling and introduce a dedicated `highlight_style`.
- Adjust default theme colors to use explicit RGB values for better consistency.
Implemented full markdown table support:
- Parse tables with headers, rows, and alignment.
- Render tables as a grid when width permits, falling back to a stacked layout for narrow widths.
- Added helper structs (`ParsedTable`, `TableAlignment`) and functions for splitting rows, parsing alignments, column width constraints, cell alignment, and wrapping.
- Integrated table rendering into `render_markdown_lines`.
- Added unit tests for grid rendering and narrow fallback behavior.
- Introduce new `owlen-markdown` crate that converts Markdown strings to `ratatui::Text` with headings, lists, bold/italic, and inline code.

- Implement `:markdown [on|off]` command to toggle markdown rendering.
- Update help overlay to document the new markdown toggle.
- Adjust UI rendering to conditionally apply markdown styling based on the markdown flag and code mode.
- Wire the new crate into `owlen-tui` Cargo.toml.
- Set `default_syntax_highlighting` to true in core config.
- Added language‑aware syntax selector (`select_syntax_for_language`) and highlighter builder (`build_highlighter_for_language`) with unit test.
- Integrated new highlight module into `ChatApp`, using `UnicodeSegmentation` for proper grapheme handling.
- Simplified `should_highlight_code` to always return true and removed extended‑color detection logic.
- Reworked code rendering to use `inline_code_spans_from_text` and `wrap_highlight_segments` for accurate line wrapping and styling.
- Cleaned up removed legacy keyword/comment parsing and extended‑color detection code.
- Introduce `message_border_style` to render message borders with a dimmed version of the role color.
- Add `dim_color` and `color_to_rgb` helpers for color manipulation.
- Update role styling to use `theme.mode_command` for system messages.
- Adjust card rendering functions to accept role and apply the new border style.
- Add `seen_meta` set and `push_meta` helper to avoid duplicate entries when building model metadata strings.
- Extend metadata handling to include context length fallback, architecture/family information, embedding length, size formatting, and quantization details.
- Introduce `populate_model_details_cache_from_session` to load model details from the controller, with a fallback to cached details.
- Update `refresh_models` to use the new cache‑population method instead of manually clearing the cache.
