/* ─────────────────────────────────────────────────────────────────────────
   GYMNAST — public website
   Plan: GYMNAST_WEBSITE_MASTER_PLAN.md. Light, editorial, restrained: white
   paper, near-black ink, one accent. Accent and ink come from the member app's
   white theme (lib/features/portal/presentation/theme/customer_theme.dart), so
   the site matches the real app screens it shows.
   Product images are REAL app screens rendered by the test/_screenshot_*.dart
   harnesses with sample data — never drawn mockups.
   Static, no build step, no animation library. Every page reads without JS.
