Key notes

Web: Next.js app (App Router), server-rendered pages, client hooks for auth state.
API routes: Authentication, admin approvals, listings CRUD (soft-delete), profile update.
Data: Postgres via Prisma (models: User, Listing, ListingTranslation, ListingImage, VerificationToken).
Mail: SMTP (smtp.sohva.org) + DKIM signing for verification emails.
Auth: Email/password, verified+approved requirement, JWT session cookie (session_token), roles.
