/* ============================================================================
 * Pia Hero Animation — Component CSS
 *
 * A drop-in hero illustration that cycles through three Pia mechanics:
 *   1. Voice input → laptop ("Created on your device")
 *   2. Conversations → laptop ("Stored on your device")
 *   3. Laptop → encrypted cloud sync ("End-to-end encrypted")
 *
 * Everything is scoped under .pia-hero-anim, so this CSS will not leak
 * into the rest of your site. Keyframes are prefixed `pha-`.
 *
 * Required at runtime:
 *   - pia-hero-animation.js (vanilla, no dependencies)
 *   - 'Outfit' (UI/captions) and 'Instrument Serif' (italic tagline) web fonts
 *     loaded somewhere on the page. The component will fall back to system
 *     fonts if they are missing, but the editorial feel depends on them.
 *
 * Sizing:
 *   The component is responsive — fills its container width, 1:1 aspect ratio,
 *   capped at max-width: 420px. Drop it where you already render the hero
 *   persona and it will size to that slot.
 * ========================================================================== */
