/*
 * Legion AI — Obsidian design system (WS4, 2026-07-01)
 *
 * One token system, two themes. html.dark is the default ("obsidian":
 * near-black, never pure black); html.light inverts the same structure.
 * The anti-flicker IIFE in each page's <head> sets the class before paint.
 *
 * Type system (site-wide, exactly two families):
 *   --font-display  Fraunces  — headlines + industry index names only
 *   --font-body     Inter     — everything else
 *
 * Accent discipline:
 *   --accent        violet — interactive elements ONLY (primary buttons,
 *                   focus rings, active states, links on hover)
 *   --value         green  — customer value figures ONLY (hours, dollars)
 * Nothing else gets color. No cyan, no gold, no per-section palettes.
