Architecture

Phone and browser talk to one Next.js app. The app holds the rules. SQLite holds the data on a volume so a restart does not wipe the desk.

Flow

A person registers as a provider or someone looking. Providers list only in their category: ghar, kitchen appliances, cars, bikes, or a home-service visit. Buyers filter and inquire. Landlords still collect kiraya and watch renewals. The super admin can turn a category off or pack a white-label copy with limited categories.
