   Light editorial theme in the Google Antigravity idiom: a white page, one very
   large type scale, hairline rules instead of boxes, pill controls, and colour
   that appears only where it means something — the caret that types the
   headline, and the aurora behind a product shot.

   One stylesheet, no framework.
