/* =========================================================================
   Strong & Fit with Jerin — stylesheet
   Design tokens:
     Ink   #121210  (near-black, primary surface)
     Bone  #EDEAE1  (paper surface, cool-stone not warm-cream)
     Brass #C9A227  (primary accent, from the JF shield)
     Ember #8B2E2E  (secondary accent, from the shield trim)
     Steel #6B7280  (muted neutral)
   Type:
     Display — 'Anton' (condensed poster weight, echoes the brand poster)
     Body    — 'Inter'
     Utility — 'JetBrains Mono' (meta labels: dates, categories, stats)
   Signature: a hand-torn "chalk" underline accent + shield-notch corners
   on featured cards — a nod to gym chalk and the JF shield motif.
