/* FilmScan — the SwiftUI look in CSS.
 *
 * The app is `.preferredColorScheme(.dark)` with `.tint(.orange)`, so the
 * palette below is the iOS system dark palette and SwiftUI's `.orange`.
 * `.ultraThinMaterial` becomes a blurred translucent panel; the iOS type
 * scale (largeTitle, headline, subheadline, caption, caption2) is kept as
 * named sizes so the screens read the same as the Swift source.
