/* ============================================================
   COLOR SYSTEM — graphite + ivory dual-surface, teal/violet AI accents
   Every shared component reads --ink/--ink-soft/--paper/--surface/
   --surface-tint/--line. :root defines the light ("ivory") values;
   wrapping any <section> in .on-dark redefines the same names to
   their graphite equivalents — one ruleset, two themes, no per-
   component duplication. --brand stays the name for the single
   primary accent (teal) so every existing component that already
   reads var(--brand) re-themes automatically.
