even in the TUI we need proper syntax highlighting for source code and diffs and I don't know how markdown comments are handled, if they are rendered or showing source - I would prefer a pseudo-rendered. markdown look so that emphasies and titles and things like that show in the terminal. but for source and diffs definitely need syntax highlights

Implemented in aafde7e.

Source-file previews now use Syntect's bundled grammars, selected by filename with first-line/shebang fallback; unknown text remains plain and legible.
Commit and pull-request unified diffs use the bundled diff grammar, giving metadata, hunks, additions, and deletions distinct syntax colors.
Home activity content and issue, pull-request, milestone, and comment text now use a Ratatui-native pseudo-rendered Markdown presentation for headings, emphasis, strong text, lists, links, inline code, and fenced blocks.
Existing work-item metadata line breaks are preserved through Markdown rendering.
Syntax output is cached by exact path/content so the TUI redraw loop does not repeatedly parse the same large file or diff.
TESTING.md now covers syntax, Markdown, fallback, and the current unconditional q behavior.

Verification:

cargo fmt --all -- --check
RUSTFLAGS="-D warnings" cargo check --workspace --all-targets
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace (46 tests)
Color-capable interactive PTY against the configured server: verified a real commit diff emitted distinct truecolor context/addition styles
Opened TESTING.md through the live repository browser and verified filename-driven source syntax colors
Selected the Markdown implementation comment in live Home activity, scrolled its preview, and verified list structure plus inline-code styling

This is TUI-only, so no iPhone release build was performed as requested.
