   Layout: a long, quiet Apple-style scroll on white. One 1200px column. Product shots carry the story;
   type does the rest. Colour comes from the app's own tokens (app/lib/theme/tokens.dart); the glossy blue
   is reserved for primary actions. One dark chapter (security) is the only change of ground. */
