/* progress.css — the progress page (site/progress.html): one sky, four cards, one link to the whole map.
   Ported 2026-09-25 from 1_ACTIVE/progress_reporting_CLAUDE/css/style.css. Every class is pr- prefixed
   because the book's CSS already owns .card, .hero, .bar, .chip, .toast. Paper, ink, lines and the three
   type families are the book's tokens, so the Design lab's paper and fonts apply here too. Gold is the one
   colour that means "yours"; the canvas reads the --star-* tokens from .pr-sky. */
