Introduce a Hacker News-inspired time-decay trending score that ranks projects by engagement velocity (votes + weighted comments) divided by age, replacing the static all-time-popular sort on the homepage. - New `src/lib/trending.ts`: scoring formula, period filtering, generic rankByTrending utility - New `/trending` page with Today/Week/Month/All Time period tabs and top-3 spotlight cards - Homepage "Featured Projects" now shows genuinely trending projects instead of all-time vote leaders, with "See all trending" link - ProjectGrid default sort changed to "Trending" with fire icon - "Trending" nav link added to header - Zero new dependencies; all ranking computed client-side - 0 TypeScript errors, build passes, bundle under budget https://claude.ai/code/session_0131A8wmcDCSmrB22iU5d4Rs

Use ranked length for trending grid empty-state logic
When sortBy is trending, rankByTrending(enriched, 'week') can return an empty array if the fetched projects are all older than 7 days. In that case the component still uses projects.length for result counts/empty-state branching, so users can see a nonzero "projects found" count with an empty grid and no empty-state message. This shows up in low-activity periods and makes the page look broken.

Check enrichment query errors before seeding user state
The vote/bookmark enrichment path builds votedIds/bookmarkedIds from votesResult.data and bookmarksResult.data without checking votesResult.error or bookmarksResult.error. If either query fails (for example, transient Supabase/API failures), every project is seeded as not voted/not bookmarked, and because cards use skipStatusFetch, the UI can stay incorrect for that session.

…mentation - Fix empty state logic in ProjectGrid to use enrichedProjects.length instead of projects.length - Add error checking for vote/bookmark enrichment queries in TrendingPage - Extract magic numbers to named constants (TRENDING_POOL_MULTIPLIER, MIN_TRENDING_POOL_SIZE, FEATURED_PROJECTS_COUNT) - Improve error handling with proper logging in development mode - Add race condition protection for loadProjects in both ProjectGrid and TrendingPage 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Vishal Sachdev <vishalsachdev@users.noreply.github.com>
The previous fix commit (f37268c) imported FEATURED_PROJECTS_COUNT in database.ts but only FeaturedProjects.tsx uses it. TypeScript's noUnusedLocals check causes `tsc` to fail, which breaks the Vercel deployment since `npm run build` runs `tsc && vite build`. https://claude.ai/code/session_0131A8wmcDCSmrB22iU5d4Rs
