 * AMAYA Hubs — Shared Site System v1

 * Premium primitives every hub uses to build above the floor.
 * Each hub overrides brand tokens (--bg, --ink, --accent, --serif, --sans)
 * in its own <style> block above this import. Everything below is brand-neutral.
 *
 * Built around: native CSS, no framework, no build step, no JS dependencies
 * except the companion site-system.js for reveals + accordion.
