fix(ui): apply themed background to input area and app surface#2182
Merged
Conversation
The theme system defines SURFACE.bg and SURFACE.bgInput but no component applied them — the entire UI rendered on the terminal's default background, causing: - Input text invisible when terminal bg differs from theme - No visual separation between card stream and input area - Theme surface colors completely unused Add backgroundColor to three layout containers: - App root Box → SURFACE.bg (app canvas) - ComposerArea wrapper → SURFACE.bgInput (input dock) - PromptInput bordered Box → SURFACE.bgInput (input field) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Clean, small theming change — applies the theme's surface colors at the Ink-Box level: SURFACE.bg on the root app row and SURFACE.bgInput on the composer/prompt-input boxes. Unlike #2223's OSC 11 approach, this only paints the app's own rendered region (no terminal-state mutation to restore), so it's self-contained and safe. Tokens exist for every theme. I approved the workflow run; good to merge once CI is green. Note it's complementary to #2223 (in-app box bg vs actual terminal bg) — you may want only one depending on the look you're after, but they don't conflict.
