#254 feat(ui): add favicon from Meridiona tray icon

[Anonymous]

Originally created by: Akarsh-Hegde

Summary

• The dashboard had no favicon — browser tabs showed a blank/generic icon.
• Added favicon.ico (16/32/48 px multi-size), icon.png (512×512), and apple-icon.png (180×180) to ui/app/, all derived from the Meridiona spirograph mark used in the macOS tray bar.
• Next.js App Router picks these up automatically by filename convention — no changes to layout.tsx needed.

Test plan

• [x] Pre-push hook (cargo fmt + clippy + cargo test + UI build) — passed
• [ ] Visual: open http://localhost:3001 and check the browser tab shows the Meridiona spiral icon

favicon.ico regenerated with all three sizes — pushed as a2b7766.

Fixed:

• favicon.ico now embeds 16×16, 32×32, and 48×48 frames (PNG-in-ICO). The original was missing the 48px frame despite the PR description claiming it was present. Verified by parsing the ICO directory: ICO contains 3 image(s): 16x16px, 32x32px, 48x48px.

Not yet resolved — icon.png compression:
The icon.png size (139 KB) requires lossy quantisation (pngquant) or lossless zopfli recompression (oxipng) to hit the 40–60 KB target the reviewer suggests. Neither tool is currently installed on this machine, and lossless-only zlib re-compression (zlib.compress(level=9)) only saves ~1% on a well-compacted PNG. I can add a pngquant --quality=80-95 step once it's available, or the reviewer can run it manually before merge:

brew install pngquant
pngquant --quality=80-95 --skip-if-larger --output ui/app/icon.png --force ui/app/icon.png

Happy to do it in CI as a build-time step as well.

Other reviewer notes (no action needed):

• apple-icon.png — reviewer confirmed it's fine.
• layout.tsx — reviewer confirmed no code change needed; the file-system convention wires it automatically.
• icon.svg / manifest.webmanifest — out of scope for this PR but noted as a future improvement.

icon.png compression — still pending

The 139 KB icon.png is the one open item from the review. If pngquant isn't available locally, the quickest path is:

brew install pngquant
pngquant --quality=80-95 --skip-if-larger --output ui/app/icon.png --force ui/app/icon.png

Target is 40–60 KB. This file is fetched on every cold tab open so the size matters. Happy to approve once this is done (or if CI can run it as a build-time step as you suggested).

BLOCKED — resolve before merge

The following item is still open:

icon.png is 139 KB — needs compression before merge

This file is fetched by browsers on every cold tab open (PWA/manifest). Well-compressed 512×512 logo PNGs typically sit at 40–60 KB. The current file is ~3× oversized.

Fix (one command):

brew install pngquant   # if not already installed
pngquant --quality=80-95 --skip-if-larger --output ui/app/icon.png --force ui/app/icon.png

Then commit the smaller file. Everything else in this PR is good to go.

Done — icon.png compressed 139 KB → 52 KB (63% reduction) via pngquant --quality=80-95. Committed as 842490b.

Within the 40–60 KB target.
