/*
 * orc-tokens.css — Orchestrace "Meridian" token system (Phase 1, additive)
 *
 * Tier 1 primitives -> Tier 2 semantic -> Tier 2b legacy bridge.
 * Dark theme uses the .dark-theme CLASS ONLY — never the data-theme
 * attribute, which belongs to JS/ECharts (see docs/superpowers/specs/
 * 2026-07-24-orchestrace-identity-system.md §2 and the design-system inventory).
 * Consumed ONLY by orc-* primitives in Phase 1; existing surfaces are
 * untouched and no legacy token is declared or re-pointed here.
 *
 * Meridian = deep-sea teal current on cool paper (owner-selected 2026-07-24,
 * reconciled from the earlier Copperline direction). VALUE + honest-name change
 * only: the neutral ramp is renamed cool-*, the accent teal-* / current-*
 * (full rename map in the identity spec §2 decision record). Glow-free
 * material system unchanged; shadows preserved exactly.
