Hugh KaznowskiandClaude Sonnet 5 00c21c8032 Trim comments across Rust and webapp source to direct one-liners (ticket 030)
Pass over src/*.rs, webapp/src/**, and the in-app "?" docs prose:
condensed multi-paragraph doc comments to single lines that state the
non-obvious why, deleted comments that only restated adjacent code, and
tightened the Docs.tsx help-panel wording. No logic, structure, or code
formatting changed — verified via cargo test (143 passed) and
tsc -b && vite build.

// A theme file is a CSS file with one `:root { --c-*: ...; }` block defining every variable in `THEME_CSS_VARS`; `useSettingsPanel` applies the selected one as an unscoped stylesheet only while no built-in `html.<scheme>` class is present, so it wins the cascade without rewriting the selector.
