   HH Labs — Landing page
   Concept: "AI Playground" — warm cream canvas, bold colour,
   sticker-like cards with hard shadows, playful shapes.
   Every section owns a colour "scene"; the page background
   follows the section in the middle of the viewport.
   Themes: light (default by OS) / dark via [data-theme].
