/* ============================================================
   THEME — Terminal (VT100 CRT Phosphor)
   -----------------------------------------------------------
   This is the ONE FILE users swap to reskin their site.
   Replace this file with any other theme.css to change the
   entire look & feel. Tokens only — no component CSS lives here.

   TOKEN CONTRACT
   -----------------------------------------------------------
   Every theme MUST declare every variable in this file, even
   if it sets it to a neutral value (e.g. --blur-md: none;).
   That's what guarantees a clean one-file swap.

   Slots:
     Surfaces : --paper, --paper-raised, --paper-sunk, --paper-glass
     Ink      : --ink, --ink-soft, --ink-faint, --graphite, --muted
     Lines    : --guide, --guide-soft, --hair, --hair-soft
     Primary  : --ai, --ai-ink, --ai-wash           (cyan — terminal links)
     Seal     : --shu, --shu-wash                    (error red)
     Accent   : --ochre, --ochre-wash                (warning amber)
     Code     : --code-bg/ink/muted/accent/green/blue
     Type     : --font-display/script/serif/sans/mono
     Radius   : --r-sm, --r-md, --r-lg
     Shadow   : --shadow-sm, --shadow-md, --shadow-lg
     Blur     : --blur-sm, --blur-md, --blur-lg     (glass only; else 'none')
     Glow     : --glow-sm, --glow-md, --glow-lg     (emphasis / rim / phosphor)
     Motion   : --duration-fast, --duration-normal, --duration-slow, --ease

   FONT NOTE
   -----------------------------------------------------------
   A terminal has no serif and no handwritten script. To keep
   the contract intact without breaking the mood, every font
   slot — display, script, serif, sans, mono — points at
   --font-mono. The contract survives; the CRT stays pure.
