/* Case Tracker: USCIS Status landing page.
   Derived from the app: iOS system UI (white / systemGray6 grounds, system blue accent, 12-16px radii,
   flat buttons, per-stage status colors from USCISStatus.swift) plus the App Store marketing frames
   (deep navy gradient with faint stars, white display type, light-blue subtitles).
   Changes vs. the dnapps-landing template: flat buttons (no slab edge), navy stages instead of tinted blobs,
   star motif instead of blob/sparkle, Manrope instead of Nunito, timeline + forms components added.
   Cache-bust with ?v=YYYYMMDDx on the <link> whenever this file changes. */
