/* Pistachio /try marketing landing (AND-1540). Same tokens and look as the web app (src/client/tokens.css, style.css):
   white canvas, SF system type, black/white UI; the only color is the cat and her Siri glow around the orb.
   Dark mode follows the system (iOS dark tokens from design/src/kit.css); every text pair is AA, checked numerically.
   Light secondary ink is rgba(60,60,67,.75), not iOS's .6 (3.4:1 on white): 5.2:1 on #fff, 4.9:1 on cards, 4.8:1 on the field fill.
   One black (primary) button per screen: the hero or final CTA, the email Join, Watch "Yes", or Join the beta when install shows;
   the top-bar pill, Share and "Not yet" are grey. Font sizes are px, so every row wraps and long words break at 200% text. */
