   tokens.css — THE SINGLE SOURCE OF TRUTH  ·  v2 "MERIDIAN" (redesign)
   ----------------------------------------------------------------------------
   Concept: a precision instrument for finding talent. Cool near-black slate,
   the owner-chosen indigo (#4F46E5) → cyan (#22D3EE) accent used SPARINGLY as a
   signal, not a glow. Hairline rules, a faint coordinate grid, technical mono
   numerals. Gender-neutral, confident, editorial-tech.
   ----------------------------------------------------------------------------
   Palette hues are LOCKED by the owner (indigo → cyan). Shades were refined
   ≤10% vs. the previous "Midnight Steel" set; no new hue families.
   Every text pair below is WCAG-AA verified (see brand-guide.md §Contrast).
   Rule for all agents: use ONLY these tokens. Do not invent colors/type/motion.
   NOTE: historical names --violet-* / --coral-* are KEPT so downstream CSS need
   not change; they carry indigo (violet-*) and cyan (coral-*) values.
