What to build

Expand the one-item tracer bullet into the cohesive Verified Feed experience: six to ten persisted CapCheck-vetted videos, finance-category filters, text search, empty/reset states, responsive cards, and consistent navigation between discovery, analyzer, and video detail.

The page must remain a calm consumer trust tool rather than a dense dashboard. Use thumbnail cards, concise TLDR copy, visible category and No cap status, and one clear path to the evidence-rich detail page.

Acceptance criteria

• The feed supports Investing, Credit, Taxes, Budgeting, and Retirement categories plus an All state.
• Search matches useful title, creator, TLDR, and category text with an explicit clear/reset control.
• Cards show YouTube attribution, thumbnail, duration, TLDR, category, Cap Score label, and last-checked time without loading grid iframes.
• Desktop uses a restrained responsive grid; mobile uses one column with scrollable or wrapping category controls and no horizontal page overflow at 375px.
• Loading, empty, no-match, stale, deleted-video, and database-error states are designed and tested.
• Keyboard navigation, focus visibility, headings, card links, and reduced motion follow the shared design spec.
• Component tests and desktop/mobile Playwright exercise every search, category, reset, card, navigation, and recovery control.
• An Impeccable critique/audit is run if available after the real UI exists, with actionable findings resolved or recorded.
