/* ============================================================================
   Design system — clean & professional, not neo-brutalist.

   Structural palette (fixed, from brand):
     --ink      #08090A   Black       — primary text / dark bg / primary CTA
     --carbon   #222823   Carbon Black — dark-mode surfaces
     --charcoal #575A5E   Charcoal    — secondary text, dividers
     --lilac    #A7A2A9   Lilac Ash   — brand accent (focus, active states)
     --snow     #F4F7F5   Bright Snow — light bg / text-on-dark

   Semantic palette (UX only — status communication, not brand identity):
     --success  achievement met / OK
     --danger   not met / rejected
     --warning  soft caution (duplicate flags, below-minimum notices)

   Cards use soft elevation (shadow) instead of heavy outlines. Typography
   leans on weight + size for hierarchy rather than blanket uppercase/black.
