/* =============================================================================
   Stanford AI Training Hub — shared shell + design system (hand-written, no
   frameworks). Loaded by every public hub page: /, /browse, /tracks/:id,
   /whats-new, /learning-paths and /library/:id.

   Visual direction: the approved "AI Catalyst" editorial mockup —
     • Newsreader (serif, 500/600) for huge display headings with tight
       line-height and negative tracking; Manrope for body/UI; DM Mono for
       eyebrows, kickers, labels and meta (uppercase, letter-spaced).
     • Palette: ink #2e2d29 · ink-soft #53565a · forest #2e2d29 (dark surface:
       brand mark, featured cards, live-session band, footer) · teal #b1040e
       (THE interactive accent) · mint #f2dcd9 · lime #d98c8c (accent-on-dark)
       · paper #ffffff (page) · white #ffffff (cards) · line #e4e1db.
     • Cardinal #8c1515 appears ONLY in the one-line institution strip.
   Contrast (WCAG 2.2 AA): teal on paper 4.7:1, on white 4.9:1; ink-soft on
   paper 7.1:1; forest on paper 13.9:1; lime on forest 12.3:1; #820000 on
   mint 6.0:1; #c6c3bd on forest 9.9:1.
