/* =============================================================================
 * Blueprint — CoryAI design tokens (v0.1, light mode)
 *
 * The single source of color, type, radius, spacing and elevation for both
 * blueprint/app and blueprint/brochure. Components never hard-code a hex value;
 * a future dark theme redefines these tokens and nothing else.
 *
 * Color follows 60-30-10:
 *   60% dominant  — warm drafting paper (--paper / --surface)
 *   30% secondary — deep navy (text, dark bands, device frames)
 *   10% accent    — electric blue, reserved for actions: CTAs, the mic, links,
 *                   the active tab. If it isn't tappable, it usually isn't blue.
 * Green means confirm/saved only. Wood is a warm brand accent (eyebrows,
 * illustrations), never a UI state.
 *
 * Every text pairing here meets WCAG AA (4.5:1) on paper, paper-2 and surface;
 * measured when these values were set (Blueprint v0.1).
