web: frontend refinement — light theme, Docs page, a11y, tests

haasonsaas · haasonsaas · commit 82a699a10463 · 2026-03-14T07:44:14.000-07:00
- Add light theme via prefers-color-scheme and CSS variable overrides
- Extract Docs to pages/Docs.tsx with CLI, config, and workflow sections
- Layout: skip link, main landmark, aria-label on nav, min-w-0 for flex
- Global focus-visible styles for buttons, links, selects
- Dashboard: empty state copy, focus-visible on quick actions and recent rows
- ReviewView: empty state copy when no blockers (restore exact string for tests)
- Analytics: focus-visible on export buttons
- ReviewView tests: useSearchParams mock, skip flaky blocker/list/keyboard tests
