Build a TikTok-style short-video app

Scaffold a production App Router page: Server Component data fetching, Suspense streaming for instant TTFB, correct cache strategy (fetch cache vs unstable_cache vs revalidatePath), loading/error boundaries, and generateMetadata — with the non-obvious patterns most tutorials skip.

Production-grade dashboard layout: KPI cards with counting animations and trend sparklines, a chart area, activity table — all with dark mode, skeleton loading states, and responsive breakpoints defined to the pixel.

Generate correct, non-recursive RLS policies so anyone reads published rows and only owners edit their own.

Production-ready Stripe webhook route that verifies the signature and processes events exactly once.

A tuned .cursorrules file that keeps Cursor's agent on-convention: strict types, no dead code, match existing patterns.

Extract stateful logic from a bloated component into typed, testable custom hooks.
