/**
 * S2040 (v5 Phase 2 — Marissa+Steve).
 * ICLI = Iboga Component Lib Incognito.
 *
 * Foundational primitives for the v5 Steve-cinematic surface. CSS
 * vars layered on top of incognito-v4's --accent / --card / --border
 * tokens so every component reads from the same theme.
 *
 * Components added:
 *   icli-section-header  (S2041)
 *   icli-button          (S2040)
 *   icli-card            (S2040)
 *   icli-modal           (S2046 scaffolding)
 *   icli-tabs            (S2040)
 *   icli-metric-chip     (S2040)
 *   icli-empty           (S2047 scaffolding)
 *   icli-skeleton        (S2048 scaffolding)
 *
 * Each includes light/dark + responsive baked in. Steve cinematic
 * treatment (gradients, motion, hero meters) layers on top per-page.
