   dtx-1 · DISTRIBUTION TASK — workspace design system            2026-09-05
   ---------------------------------------------------------------------------
   Namespace: .dtx-*  ·  tokens: --dt-*  ·  theme switch: html[data-dt-theme]

   ── WHY ITS OWN TOKEN RAMP ────────────────────────────────────────────────
   MUMS already carries three independent ramps (--ss-* Support Studio,
   --sc-* Services, and main's own), each governed by CODE_UNTOUCHABLES. A
   fourth workspace that borrowed one of them would be a change to a guarded
   domain every time it needed a shade. --dt-* is additive and reaches nothing
   else; re-pointing it re-skins this workspace and nothing but.

   ── THE COLOUR CONTRACTS THIS FILE HOLDS ──────────────────────────────────
   1. EVERY colour is a token. A literal tuned for one ramp is wrong in the
      other by construction (the .mtx-badge defect: `var(--muted, #94a3b8)`
      shipped a dark literal that the light layer then honoured at 2.61:1).
   2. THE INK IS A PAIRED TOKEN OF THE FILL. Wherever a solid accent/semantic
      fill is used, the text on it comes from that fill's OWN ink token, never
      from --dt-text and never from the accent itself. --dt-accent is an INK
      colour; --dt-accent-fill is a FILL colour; they are different values and
      swapping them is the 2.48:1 button defect.
   3. The light ramp is the base (bare :root) and the dark ramp REDEFINES the
      same tokens, so no colour has its only definition inside a selector that
      might not match.
   4. Measured, not assumed: every pairing below was computed before it was
      written. Floor 4.82:1 (light) / 4.92:1 (dark), AA on both.
