- web/static/manifest.webmanifest: name/short_name/start_url=/dashboard/
display=standalone/theme_color/background_color + three icons (192, 512,
512-maskable with ~12% safe-zone padding)
- web/static/sw.js: minimal SW — install caches /static/* shell assets,
fetch is network-first with cache fallback on GETs only, skips /mcp/
and non-GETs entirely. CACHE_NAME versioned for clean activate-time
prune.
- cmd/icongen: stdlib-only generator that produces the three PNG icons
from a stylised "p" monogram. Run once at brand-change, commit output.
- web.init() registers .webmanifest → application/manifest+json with
mime.AddExtensionType so Chrome accepts the manifest at all
- layout.tmpl + login.tmpl: manifest link, apple-touch-icon, theme-color,
apple-mobile-web-app-* metas, inline SW-register on load (silent on
failure — older browsers still work)
- design.md gets §"PWA install (Phase 3j)"; CLAUDE.md "Out of scope"
drops the Phase-3j line and adds push/background-sync as the
remaining Otto-PWA territory
- 4 new tests cover manifest MIME, sw.js delivery, all 3 icons, layout
