/* GRID//NODE ACCESS//GATE v0.15.22 — private-beta authorization overlay.
 *
 * Style rules:
 *   - No new design tokens. Reuses --font-m, --font-d, --text, --text-mid,
 *     --text-dim, --cyan family, --lava-core, --panel, --surface, --border.
 *   - Uses existing gn-* class family where possible.
 *   - Extends .gn-card-* via the panel surface (.gn-beta-gate__panel inherits
 *     instrument-well inset depth).
 *   - One focal glow source only: AUTHORIZE // ACCESS CTA.
 *   - Reduced-motion respected: no jitter, no shake, no collapse animation.
 *   - All durations and easings use the existing cubic-bezier vocabulary.
