/*
 * Path: css/components/hero.css
 * Purpose: Hero component — logo box, tagline, actions visibility, replay, chevrons, keyframes
 * Boundaries: No global button visuals; base .btn/.cta will live in components/buttons.css
 * Depends on: css/core/tokens.css, css/core/layout.css
 * Version: 0.9.0 (pre-1.0)
