- M5: 📱 toolbar button → modal with a client-side QR of location.origin
(shareable when opened via the LAN IP) + localhost tip
- M4: manifest.webmanifest + icon.svg + sw.js (network-first, never intercepts
/term or /hook) + registration in main.ts; apple-touch + theme-color meta
- Browser-verified: QR canvas renders, SW 'controlled', manifest linked,
no console errors. 199 tests green, build ok.
