The SVG tracer export failed, so the icon was designed collaboratively from
scratch: a wooden «Э» tile with a ✻ score-subscript in Spectral Bold, wood
grain and diagonal light/shadow. Construction is specified in fractions of the
side in docs/ICON_BRANDBOOK.md; the reference generator, pinned Spectral font
and committed masters live in assets/icons/brand/.
One master -> the whole set (assets/icons/brand/build-set.mjs + build-android-res.mjs):
- web (ui/public): favicon.svg (light+dark via prefers-color-scheme), favicon.ico,
apple-touch, PWA any + maskable (+ dark variants), og-image reskinned to
«Эрудит» / Игра в слова
- Capacitor layers: ui/assets/{icon,icon-foreground,icon-background}.png
- Android launcher res, all densities, NO inset, + monochrome themed layer
(anydpi xml: background+foreground+monochrome)
- manual-upload art: assets/icons/brand/{vk,tg,store} (square, no rounding)
Primary variant light; dark where the platform can theme (favicon.svg). The old
LiberationSans generator (assets/icons/build) is removed; docs/ICONS.md retargeted
onto the single master. ANDROID_PLAN icon-rebrand item marked done.
Make the web SPA an installable PWA and surface it to users:
- manifest.webmanifest + an install-only service worker + 192/512/maskable
icons (ui/public); PWA head tags in index.html; the .webmanifest MIME type
registered in the gateway (the distroless image has no /etc/mime.types).
- Platform-adaptive install CTA (components/InstallApp.svelte + lib/pwa):
one-tap on Chromium, manual Add-to-Home-Screen instructions on iOS Safari,
hidden elsewhere / once installed / inside a Mini App. Shown under the
logged-out login card and at the bottom of Settings.
- The landing gains a third entry linking /app/ (the brand tile), with a
caption under all three (Telegram / VK / Веб-версия).
The service worker is navigation-only (network-first, cached-shell fallback);
hashed assets and the Connect stream are untouched. It exists to satisfy
Chromium's installability requirement and is the single growth point for a
future opt-in offline mode.
Tests: pwa.ts unit tests; a webui probe (manifest/sw.js content-type + the
SPA-fallback-to-HTML trap); e2e for the one-tap CTA, the iOS instructions
modal and the landing web entry. Docs: ARCHITECTURE §13, FUNCTIONAL (+ru),
gateway README.
