/* Proton Drive for Linux — app stylesheet.
 *
 * Colours come from the libadwaita palette (var(--accent-bg-color),
 * var(--success-color), ...) so the app follows the system accent, light/dark
 * and high contrast. The one exception is the photo viewer, which always sits
 * on a near-black backdrop and so uses fixed light-on-dark colours. The Proton
 * purple accent is opt-in and lives in its own provider (see main.rs).
