# Tech Design: [Project]

## Core engine / key API
The one thing the app is really built around (maps, payments, ML, search,
realtime), if it has one. Name it first, everything else follows from it.

## Framework
[Next.js for web / Expo for mobile / ...] and the one-line reason.

## UI
[Tailwind + shadcn/ui / NativeWind / ...] and why.

## Database + auth
[Supabase / on-device storage / none] and why. Skip it if your wedge is "no
login".

## Data model
The core tables or shapes, kept minimal.

## Deploy
[Vercel / EAS / ...], connected today so every push ships.
