## Summary
Closes#30.
- Replace old infinity brand mark with the cyan Greek-key (meander) Hesychia emblem
- Update web favicons / PWA icons (`public/`), Capacitor source art (`assets/`), and regenerate Android launcher + splash densities
- Wire mark into Header / Header2, Sign In / Sign Up, and Sidenav branding
## Test plan
- [ ] Favicon + apple-touch icon show new mark in browser tab / home screen
- [ ] Header and auth screens show mark + Hesychia wordmark
- [ ] `npm run assets:generate` already run; Android launcher / splash use new art
- [ ] Old infinity artwork no longer present in `assets/` / `public/` brand slotsReviewed-on: #46
## Summary
- Closes#18
- Replace stale `favicon.jpg` / old ICO with multi-size `favicon.ico`, PNG variants (`16x16`, `32x32`), `logo192.png` / `logo512.png`, and `apple-touch-icon.png` generated from the new brand mark
- Point `index.html` and `manifest.json` at the new assets; drop the CRA placeholder app name in the manifest
## Test plan
- [ ] Hard-refresh the app (or clear site data) and confirm the new logo appears in the browser tab
- [ ] Check DevTools Network for `favicon.ico` / PNG icons — no 404s and no requests for `favicon.jpg`
- [ ] On mobile Safari / iOS home-screen add, confirm apple-touch-icon looks correct
- [ ] Confirm PWA/manifest icons resolve to the new 192/512 assetsReviewed-on: #19
