/* ============================================================
   DotBinder — shared tokens + primitives (CONTRACT — Voss, frozen).
   Extracted verbatim from design/direction-1/index.html (the picked
   direction). Change requests route through Voss; pages carry their
   own page-specific CSS inline and never redefine tokens.
   Written deviation carried from D1 (on file): mono metadata/labels
   run at 13px (chips, eyebrows, table heads, dates); body prose never
   drops below 16px; all 13px text passes 4.5:1 in both themes.
