The Linux packages only installed a single 1024x1024 hicolor PNG, and
Plasma's icon lookup returns nothing for a lone oversized icon — confirmed
with kiconfinder6 under Papirus-Dark. Generate 16-1024 px PNGs from the
favicon and point electron-builder at the directory so every standard
hicolor size is installed.
desktop/ serves the normal frontend build over a privileged app://j621
scheme, so localStorage, OPFS, Web Workers, WebCodecs and history routing
behave exactly like Chrome. Development points at the Vite dev server;
`npm run smoke` runs headless Electron and checks the bundled app.
External links open in the system browser, and download navigations
(?download=1 or media URLs) are rerouted through webContents.downloadURL,
since preventing them cancels the download. The setup screen names the
shell's origin when the connection test fails, and the deploy docs list
app://j621 for CORS_ALLOWED_ORIGINS.
