   GOTCHA — home page.

   One visual language with the store art (store_assets/v3/final_ios):
   white into pale sky, the glossy blue ribbon, soft clay props, a tilted
   phone with the real app inside, and two-line headlines — ink first,
   blue second, Inter 800. Colours are sampled from those images.

   The content pages load this file too (for the tokens, nav, buttons
   and footer) and add css/page.css for their prose.
