Tech stack

This page is reserved for the locked implementation stack once step 4 closes.

Styling (locked 2026-07-24, see 2026-07-24-tailwind-and-uniwind-only)

• Web (apps/web, Next.js 16 + Tailwind v4): utility classes only. src/app/globals.css contains only @import "tailwindcss" and the @theme inline brand-token block. Body defaults live on <body> in src/app/layout.tsx. Helper src/lib/cn.ts composes classes.
• Mobile (apps/mobile, Expo 57 + React Native 0.86): Uniwind — Tailwind for React Native. Single CSS entry at apps/mobile/src/global.css (@import 'tailwindcss'; @import 'uniwind';), wired via withUniwindConfig in metro.config.js. className on RN components; no StyleSheet.create.
• Design prototypes (.context/designs/): static HTML using Tailwind via CDN. Light-mode only, pure utility chains — no per-surface theme.css, no theme.js, no dark mode override.
