 *
 * The palette is the app's, token for token (lib/ui/core/themes/app_colors.dart).
 * Three colours used with discipline: Royal Blue for anything active, Shark for
 * structure, white for negative space. The status trio never appears here —
 * nothing on a marketing page is dangerous, cautionary, or ready.
 *
 * The page alternates photo/black → white → black → white on purpose. It gives
 * the site a rhythm that reads as editorial rather than as a SaaS scroll, and
 * it lets the two photographs carry the emotional weight while the white
 * sections carry the argument. */
