/**
 * hero.css
 * ─────────────────────────────────────────────────────────────
 * PURPOSE: Hero / landing section styles including the boot
 *          sequence overlay, main headline, metrics cards,
 *          and particle canvas background.
 *
 * LOGIC: The boot overlay animates in sequence (JS-driven),
 *        then slides away to reveal the hero content.
 *        Metrics cards use CSS counters animated via JS.
 *        The neural particle background is on a <canvas>.
 *
 * CUSTOMIZATION:
 *   - Change boot-text strings in typing.js
 *   - Update metric labels in index.html data attributes
 *   - Adjust animation timings via --boot-step-* variables
 * ─────────────────────────────────────────────────────────────
