/* "Ideas for you?" visual cards (app-dev, 3 Nov). Drop-in for web-dev's page.
   Uses tokens.css; every value has a fallback so it also works alone. Prefix: idea- (cards), iu- (mini UI).
   How it animates: idea-cards.js adds .run to a card on screen and steps .s1 .s2 ... every 0.9 s, then loops.
   The plain styles are the FINAL state, so no JS / reduced motion / print = a calm finished picture. */
