/* ============================================================
   TG-26 — COLOUR · TG-26.2 integrated edition
   TWO REGISTERS, never mixed on one artifact:
   · PRINT — four "shaders", [data-palette="station|ultramarine|
     acid|tauceti"]. STATION leads print. All four KEPT (TG-26.2).
   · SCREEN — the folio worlds, [data-world="tuned|broadcast|
     millennium|ghost"]. Dark TUNED leads the folio. GHOST is
     EARNED — never an ungated option. PASTE-UP archived.
   Volt #C9F211 is the constant identity (--fill / the plate).
   All text-role colours pass WCAG AA (>=4.5:1) on their panel.
   --signal is graphics-only; never sets small text.
   :root == STATION (the print default).

   ════════ SCREEN REGISTER — THE FOLIO WORLDS ════════
   (ratified TG-26.1 · 02 JUL 2026 — integrated TG-26.2)
   THREE worlds + earned GHOST, set with [data-world="…"] on
   <html>. DARK TUNED LEADS THE FOLIO; STATION remains the
   default for print / CV artifacts — the register decides.
   PASTE-UP is ARCHIVED — parked in the v13 archive block,
   deliberately NOT registered here. Never back on the dial.
   THE PLATE: --plate = VOLT + SCREEN — the volt underprint
   softened by the dot-screen mask (devices.css:
   --plate-screen-mask / .tg-plate-screen). Olive #4E5F12 as a
   plate is DEAD. Exceptions, by physics and on purpose:
   light MILLENNIUM plates lavender (volt is invisible on ice —
   the same law that gives STATION its signal plate), and GHOST's
   whisper-volt plate stays: the underprint is the only colour left.
