Moving the island (or the desktop Mochi) to a monitor with a different scale could leave Mochi drawn too big and cut off, until something made him change size.

How to reproduce: two monitors at different scales (say 100 % and 150 %), Island lives on: the screen under the cursor, move the cursor to the other monitor with the island open. Mochi comes out too big and cut (or too small going the other way); it heals only when he changes size (compact ↔ expanded).

Cause

• The canvas bitmaps were sized once for the pixel ratio the window started with, but every frame was drawn at the current ratio. drawBot only resized the bitmap when Mochi's size changed, never when the ratio did.
• The (resolution: Ndppx) media query in main.ts was created once for the first ratio: after one change it never fired again, so the zoom correction missed every later monitor change.

Changes

• island.ts: Mochi's canvas resizes when the ratio changes, not only his size; the greeting canvas too.
• desktop/main.ts, mochi/minibots.ts, views/wardrobe.ts: the desktop Mochi, the mini Mochis and the wardrobe icons follow the ratio the same way (the upload canvas, the pill and the Coucou window already did).
• main.ts: the ratio watcher re-arms itself after every change, and wakes the island's frame loop so Mochi is redrawn at once even while idle (the loop stops when nothing moves). screen-changed wakes it too.

Validation

• npm test: 466 passed. tsc --noEmit, vite build: passed. git diff --check: passed.
• In the browser, with the device scale emulated at 1.25 → 2 → 1 → 1.5 → 1.75, Mochi's bitmap followed every ratio (101 → 162 → 81 → 122 → 142 px for an 81 px CSS box); before the change it stayed at 101 px.
• The bug was seen on a two-monitor Windows 11 setup; the fix has not been re-checked by hand across the real monitors yet. Linux was not tried.

Emulated scale changes don't fire media-query change events in Chromium, so the watcher re-arming itself is covered by reading, not by that test; screen-changed waking the loop is the second path for the same redraw. #899 (island screen hop) wraps the same screen-changed handler: whichever lands second needs a one-line merge.

Hi Louis 👋 — this is the first of eight pull requests from the Windows work in my fork. Each one is a single topic, built on today's main (0.5.3) and tested on its own, so you can take any of them without the others:

Fixes and robustness

• Windows/Linux: keep Mochi whole after a monitor change #892 Keep Mochi whole after a monitor change (the canvases now follow the display scale)
• Windows/Linux: build without warnings (VK_LMENU, i18n chunk) #893 Build without warnings (VK_LMENU, the i18n chunk)
• Windows/Linux: sturdier chat with model servers, clearer Claude key error #894 Sturdier chat with model servers (long answers, history budget, stream timeouts), clearer Claude key error

New feature

• Windows/Linux: OmniRoute support in Settings → Chat #895 OmniRoute support in Settings → Chat (chat provider + optional route for Coucou's AI features)

Look and feel — these change how existing views behave, which CLAUDE.md leaves to you, so they are proposals:

• Windows/Linux: slim scrollbars in the Coucou window #896 Slim scrollbars in the Coucou window
• Windows/Linux: pages of the Coucou window slide in #897 Pages of the Coucou window slide in (and toggles no longer jump to the top)
• Windows: the Coucou window opens and closes with Windows' own motion #898 The Coucou window opens and closes with Windows' own motion
• Windows/Linux: the island hops between screens instead of jumping #899 The island hops between screens instead of jumping

Two pairs touch the same lines (#892/#899, #894/#895): whichever lands second needs a trivial rebase, and I'll do it. I'd be glad if you'd consider them for Coucou, and happy to change anything you'd like done differently. Thanks for Coucou and Mochi!

Tested on real hardware: Windows 11 Pro 26H2, RTX 3090, two monitors at different scales: a 3840×2160 at 150 % (main) and a 1440×2560 portrait at 100 % next to it. Debug build of 852df6f on top of current main; npm test: 466 passed.

• Desktop Mochi (Ctrl+Alt+D), dragged back and forth between the two monitors: stays whole and the right size both ways ✅
• Island, Island lives on: the screen under the cursor, moving between monitors with the island open: Mochi stays the right size, no cut-off, both ways ✅
• Mini Mochis and wardrobe icons: sharp on both monitors ✅

So the "not re-checked by hand across the real monitors" part is covered now 🙂

This also fixes the same bug as my #809 (desktop Mochi cut off after a scale change, #344), and covers more (island Mochi, minis, wardrobe, the media query that only fired once). @Louis-CFM if you take this one, I'm happy to close #809 in its favour.
