Wayland clients cannot place themselves, so the JS setBounds drag is a
no-op there. Make the composer bar a -webkit-app-region drag handle on
Linux (input carved out with no-drag) and let the compositor move it.

Glass was macOS-only because it rode setVibrancy. Windows 11 22H2 has a
first-party equivalent in setBackgroundMaterial, so the mode now resolves
its backing per platform instead of per-OS-check: macOS keeps vibrancy,
Windows 11 gets DWM acrylic / tabbed / mica, and everything older stays on
Clear. No third-party native addon.
Two Windows-specific details the mapping has to respect. DWM only paints
the client area of a transparent window (electron#49443), so glass-capable
Windows chat windows are born transparent with the opaque themed
backgroundColor covering them while glass is off — a live Clear/Glass
toggle then needs no window recreate. And Windows exposes three backdrops
for four frost rungs, so the two heaviest both resolve to mica; the mapping
stays total so a frost saved on a Mac still renders.
Glass support is computed once from os.release() and shared: main uses it
for the persisted default and every window, preload publishes it to the
renderer so the UI can't offer a mode the window can't back.
Three small dedupes in the surfaces this feature touches:
- GLASS_SUPPORTED was a fourth inline copy of "am I on a Mac" in the
renderer. src/lib/platform.ts owns it now and the terminal's
isMacPlatform re-exports it, so the two call sites can't drift.
- The store held intensity and mode as two atoms behind two localStorage
keys with two subscriptions calling one sync. They are one setting: one
atom, one key, one subscription. A pre-mode value under that key is a bare
intensity, which has only ever meant clear -- read() keeps it there.
- global.d.ts re-declared the IPC payload as an inline union. It takes
TranslucencyState, so widening the state can't leave the bridge behind.
isChatWindow is exported and takes its search string as a parameter, because
"which windows may thin their surfaces" is the contract worth pinning.
