See SECURITY.md. Public demo has no backend, no env vars, and no auth boundary. Watchlist / alerts / spend in localStorage are allow-listed on read.
Single Vercel deployment. All analytics are pure functions over a seeded in-memory snapshot (src/lib/data-snapshot.ts + src/lib/analytics.ts). Watchlist and alerts persist in localStorage. Dark/light theme is controlled by a no-flash inline script + CSS variables.
The same data shape was previously backed by Prisma + Supabase; the client-side version keeps the full panel surface while guaranteeing a permanent green live demo.
