New `frontend/src/desktop/` module loaded only when VITE_DESKTOP=true.
Hosts the Tauri-bound UI that pure OSS doesn't need:
- tauriBridge.ts typed invoke / listen / openExternal / beginSignIn
wrappers with no-op fallbacks for `vite dev` outside
the Tauri webview.
- DesktopWelcomePage.tsx sign-in flow with browser handoff +
paste-key fallback; listens for
`velxio://auth-completed` from the shell.
- GraceBanner.tsx renders soft/hard grace banners driven by
`license_status` + `velxio://license-status`
emits from the background checkin loop.
Toggles `body.vlx-desktop-readonly` so the
editor's Save / Compile buttons disable
themselves via CSS in hard-grace.
- Esp32QemuPrompt.tsx one-time download modal when the user picks
an ESP32 board on a fresh install.
- index.ts mounts welcome conditionally and the side
panels unconditionally.
- desktop.css shared styles.
All entry points are no-ops outside Tauri so the existence of the
folder has zero effect on the OSS build.
