/*
 * Wave N — Investor demo polish — Showcase layer
 *
 * Source-of-truth CSS for the opt-in "Showcase" design layer.
 * Mocks under projects/design/mockups-investor-polish/ link to this file.
 * Implementation (Phase C) ports these tokens into apps/web/app/globals.css.
 *
 * Activation: any element under [data-showcase="true"] OR using a .showcase-* class.
 * Default surfaces (consumer in stress) MUST stay on the calm system in DESIGN.md.
 *
 * Forbidden anywhere:
 *   - rainbow / fintech-metallic gradients
 *   - glassmorphism blur
 *   - drop shadows above 0 1px 2px rgba(0,0,0,.04)
 *   - decorative motion that doesn't confirm an action or signal entrance
 *   - motion without prefers-reduced-motion guard
 *   - web-font dependence beyond an optional Inter family with font-display: swap
 */
