Adds ControlsIni — a minimal flat-INI reader for retail's controls.ini (#AARRGGBB alpha-first color tokens; case-insensitive section/key lookup; missing file returns an empty sheet with no throw). Wires the [title] color token into the vitals panel's UiLabel in GameWindow.OnLoad, with hardcoded white as the fallback. Visually a no-op (retail's [title] color is white), but proves the stylesheet plumbing end-to-end (D.2b §7). Three unit tests cover section parsing, #AARRGGBB decode, and graceful missing-file handling. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
