/* Concept 2: engineering typography.
   A menu of equal cells across the full width, light large type on a full-width grid, a pinned scene where a lime
   card sits over the drawing; a short split-screen preloader, [ bracket ] section tags, light paper cards on a dark
   page, figures as the main element; the two headline sentences stand apart with the product between them.
   Shape rule: 6-8px corners everywhere, buttons included. */
