feat: adopt brand logo, canonical web + desktop icons (ui#29 wave 2)

[rep0x]

Summary

Wave 2 brand-refresh fan-out (MIND-Studio/ui#29) for the shell repo — the unified Mind host. Pattern from drive#17 (the reference PR), plus Tauri desktop icons (shell-specific). Based on the open @mind-studio/ui 0.7.0 bump branch (chore/ui-0.7.0-brand-refresh) so <Logo /> and the React-free ./brand subpath are available. Base = the bump branch, so this diff is just the Wave 2 work.

shell stays the Mind brand — the lockup is the shared weave mark + bare "Mind" wordmark, no per-app label.

What changed

Tier 3 — in-app logo (src/app/connect/page.tsx)

• The sign-in landing's eyebrow text wordmark (Mind Shell — the everything app) is replaced with <Logo /> (mark + "Mind" in the brand serif, no label), with The everything app kept as the tagline beneath it. This is shell's primary brand surface; the shell chrome (rail / app-switcher) renders workspace tiles + the active-app label, not a Mind wordmark, so it was left untouched.

Tier 4 — canonical static web assets (mark-only, from @mind-studio/ui/brand)

• scripts/gen-icons.mjs — generates favicon + PWA/apple-touch icons (and the Tauri master, below) from the canonical mark. Adapted from drive; shell header comment.
• src/app/icon.svg — replaces the indigo-"M" placeholder with the canonical gradient weave mark.
• src/app/apple-icon.png (180), public/icon-192.png, public/icon-512.png — generated maskable/apple-touch binaries, committed.
• src/app/manifest.ts (new) — name: "Mind — the everything app", short_name: "Mind", shell description, theme_color: "#16B88A", background_color: "#07080b".
• src/app/opengraph-image.tsx (new) — dark green-glow share card, "Mind" wordmark + host-appropriate copy. Deterministic (default font, no remote fetch).
• package.json — + "gen:icons" / + "gen:tauri-icons" scripts, + sharp ^0.34.5 devDependency.
• .gitignore — shell has a blanket *.png; added negations for the three web brand icons andsrc-tauri/icons/**/*.png.

Tauri desktop icons (shell-specific)

• scripts/gen-icons.mjs also emits a 1024×1024 src-tauri/icons/app-icon.png master (white mono mark on a full-bleed Mind-Green backplate — the app-icon style).
• Ran npx tauri icon src-tauri/icons/app-icon.png (Tauri CLI was available) to rewrite src-tauri/icons/* from the master: refreshed icon.icns + icon.ico (both regenerated — no follow-up needed), the desktop PNGs (32x32, 64x64, 128x128, 128x128@2x, icon.png), plus iOS / Android / Windows Square logo variants — all committed.
• npm run gen:tauri-icons wires the master + generator together for reproducibility.
• tauri.conf.json icon paths were left unchanged (filenames unchanged — bundle.icon still points at the same three PNGs); only the artwork was refreshed.

Test plan

All run from the worktree with NODE_AUTH_TOKEN=$(gh auth token):

Command	Result
npm run wasm	✅ generated src/lib/vault/pkg (env quirk — gitignored, not part of this change)
npm run gen:icons (×2)	✅ reproducible — web + master PNGs byte-identical on re-run
npx tauri icon …	✅ rewrote src-tauri/icons/* incl. .icns + .ico
npm run typecheck	✅ pass
npm run lint	✅ exit 0 (only pre-existing repo-wide warnings/infos; none in changed files)
npm run test	✅ pass (no test files; --passWithNoTests)
npm run build	✅ pass — /icon.svg, /apple-icon.png, /manifest.webmanifest, /opengraph-image all in the route table

tauri build was not run (heavy native toolchain) per the brief — web build + typecheck + icon regeneration are green.

Pre-existing note (not introduced here): build warns metadataBase is unset for resolving social OG/Twitter image URLs — same as drive; OG image still generates.

Notes

• .icns/.ico were produced in-env via the Tauri CLI — no follow-up required.
• Wave 2 fan-out, pattern from drive#17 (+ Tauri). Anomaly vs drive: shell's tauri icon run also emitted iOS / Android / Windows Square logo PNGs that weren't previously committed — committed the full generated set (rather than a partial subset) so the desktop/mobile icon set stays consistent and reproducible.
