/*
 * AAO Portfolio — Premium Interaction Layer v12
 * ------------------------------------------------------------
 * Purpose:
 * - Preserve the proven zero-dependency v11 build and content.
 * - Add a more premium visual hierarchy, richer spatial depth and safer interaction states.
 * - Keep all effects CSS/browser-native so Cloudflare Pages and Vercel need no framework adapter.
 *
 * Change guide:
 * - Brand colors live in :root under --lux-*.
 * - Global corner softness lives under --lux-r*.
 * - Cursor glow size/intensity is controlled in .cursor-aura.
 * - 3D hero card positions are controlled by .governance-card:nth-child(...).
 * - The AI matrix node positions remain inline in index.html so content owners can change data without touching CSS.
