/* docs.css — Developer docs landing pages (iter-N+16).
 *
 * Shared chrome for /docs/api and /docs/integrations.  Builds on top
 * of the dashboard v11/v13 token system (gn-eyebrow, gn-btn, gn-dot,
 * gn-wrap, gn-hex-bg) so the docs feel native to the wallet.
 *
 * Award-worthy goals:
 *   - Cinematic hero with radial glow + grid haze
 *   - Tab-able quickstart code panels with one-click copy
 *   - Glassy resource grid that lifts on hover
 *   - Sticky filter chips on the integrations directory
