/* CVeze Design Tokens — adapted from the handoff "Lab" v0.7
 *
 * Brand thesis: a Palo Alto AI lab's product. Confident, current,
 * unfussy. The market-watching system shouldn't dress like a
 * heritage instrument — it's software, and it's proud of it.
 *
 * Three commitments:
 *
 * 1. WHITE PAPER. Crisp, near-pure white. Cards a hair dimmer.
 *    No cream, no parchment, no ash. Just clean canvas.
 *
 * 2. INK BLACK TYPE. Near-pure zinc black for everything that
 *    speaks. Generous tonal scale to nothing for support text.
 *
 * 3. ELECTRIC INDIGO. One saturated, intentional accent. Used
 *    only where conviction is being claimed: a strong match,
 *    the primary CTA, the AI moment. Never decorative.
 *
 * Light-only. Dark mode dropped per Phase-1 plan.
