/* Libut Café — public site.
   Palette and type come from the app (docs/02-design.md, lib/theme/): Stone & Matcha in light,
   Basalt & Matcha in dark, Newsreader for display, Geist for everything else. Coffee and crema
   are the caffeine cup's colours (lib/theme/cup_colors.dart). The one loud thing is the postcard
   on the home page, after the app's own "Postcard" share design. */
