# Implementer — POS-PWA

## Summary
Added PWA manifest and viewport/theme_color to POS app.

## Files
- `app/manifest.ts`: PWA manifest with standalone display, theme_color #70AD47
- `app/layout.tsx`: added viewport export with themeColor, appleWebApp config, manifest link

## Note
Removed `themeColor` from metadata export (unsupported by Next.js 16) — it now lives only in the `viewport` export.
