[backnotprop]

Pi changed its logo (https://pi.dev/logo.svg). This PR swaps the old one-tone Pi mark for the new three-colour one everywhere Plannotator draws it. Only assets and icon components change. No behaviour changes.

What changed

• packages/ui/components/ProviderIcons.tsx PiIcon (AI provider bar, AI settings) and packages/ui/components/icons/AgentIcons.tsx PiIcon (Agents tab, the Inbox's HostMark in the list row, the thread header and the empty-state cards): the three pi.dev paths with their own fills (#F09082, #4D9ABF, #F1BE58) in place of currentColor. Neither component takes a colour prop, so there is no prop to keep.
• apps/marketing/public/assets/icon-pi.svg (hero agent row, code-review agents row, Inbox page host tile), apps/marketing/public/assets/agents/pi.svg and pi-dark.svg, and .github/assets/icons/pi-light.svg and pi-dark.svg (README): now the new logo.
• apps/marketing/src/styles/global.css: removed .light .icon-pi { filter: invert(1) }. Inverting would wreck the colours, and the logo looks the same in both themes.
• apps/ios/Plannotator/Assets.xcassets/AgentPi.imageset/pi-light.svg and pi-dark.svg: both are now the new logo (same art in both appearances). Contents.json is unchanged and valid; actool compiles the catalog without errors.

Fitting

Every copy keeps pi.dev's three paths and fills exactly as published. The only edit is the viewBox: 130 130 540 540 instead of pi.dev's 0 0 800 800. That is the mark's box plus an even margin, centred on (400, 400).

• In the 800-unit box the mark drew at 59 % of the icon, clearly smaller than Claude, Codex and OpenCode.
• The old tight crop (165.29 … 469.43, used by the README and iOS) made the solid blocks look heavier than their neighbours.
• 540 sits level with them at 16, 20, 22 and 24 px. Picked from a side-by-side render of the three crops.

Proofs

Contact sheet: /Users/ramos/workspaces/research/operational/mobile-proofs/PI-LOGO-2026-10-09/index.html

• Inbox window: a compiled binary from this branch, inbox --background, a temp PLANNOTATOR_DATA_DIR and HOME, PLANNOTATOR_BROWSER=none. Claude Code, Codex, OpenCode and Pi wrote threads through inbox mcp (scripts/inbox-sim.ts). Captured in light and dark: the list, the empty-state cards, the Pi thread header, and the four marks the list drew, cloned at 16/20/24 px.
• Marketing (astro dev from this branch, light and dark): the hero agent row, the code-review agents row, and the four marketing files at 16/20/22/24 px. 22 px is the Inbox page's host tile; that page is not routable while INBOX_LAUNCHED is off.
• iOS and README: the imageset and .github files rendered beside their neighbours at 16 to 28 px. No simulator run: the list needs a paired Inbox, so that capture is not quick.

Gates

• bun run typecheck: passed.
• bun test tests packages/ui/components packages/inbox: 192 pass, 0 fail. This includes tests/favicon-surfaces.test.ts and tests/entry-assets.test.ts.
• DOM_TESTS=1 bun test on the two provider-icon DOM files: passed.
• bun run --cwd packages/ui smoke:package: passed.
• Gitleaks range scan: no leaks.
• Semgrep CE 1.172.0 with .semgrep.yml on the changed source: 0 findings.

Left out

• The README keeps its <picture> light/dark pair even though both files are now the same.
• The iOS imageset keeps both appearances, as the brief asked.
• The icon-pi class stays on the marketing <img> tags, with no rule behind it.
