   FORSTALL SCANNER — a faithful port of the Wild Imaginary West companion-app
   component (its own public/css/style.css). Every rule is scoped under
   #forstall-scanner so the app's class names and design tokens stay contained
   and never touch the rest of the case study. Values are copied from the app;
   the fonts (Bebas Neue / Rye / Alegreya / Special Elite) load in the page head.
