/* KairSun Referidos v3 — hero con energía y escalera legible.
 *
 * Dueño: agente Referidos. Se carga DESPUÉS de marketing.css: tokens, `.btn`,
 * `.wrap`, focos y reduced-motion global vienen de ahí; acá no se redefinen.
 *
 * Presupuesto de movimiento (duro): 3 loops infinitos, todos solo
 * transform/opacity en el compositor —
 *   1. `rf-orb` (orbes del hero a la deriva),
 *   2. `rf-float` (cluster de tokens + pet Legendary),
 *   3. `rf-cta-halo` (anillo del CTA respirando en opacity).
 * Todo lo demás es finito y único: entradas `rf-rise`/`rf-pop` al cargar,
 * progreso `rf-grow` y micro-destello `rf-sheen` al entrar en viewport con
 * `animation-timeline: view()` (con fallback a entrada al cargar si no hay
 * soporte). Anillos aurora y sellos: color estático, sin giro.
 * Con `prefers-reduced-motion: reduce` no corre ninguna animación.
 *
 * Rainbow: `conic-gradient` estático en un pseudo sobredimensionado; la
 * superficie opaca `inset: 2px` lo recorta a anillo.
 *   - Fallback sin `conic-gradient`: anillo sólido estático.
 * La superficie bajo el texto es opaca, así el contraste AA no depende del arco.
 *
 * Contador de escalones: `counter(rf-step)` en `.rf-card__top::after` y en
 * `.rf-legend__visual::after` → "1/10"…"10/10" sin tocar el HTML (ES+EN
 * quedan idénticos por construcción). Números fijos y honestos.
 *
 * Reglas duras: sin JS, sin inline, sin `!important`, fuentes locales, focus
 * visible heredado, touch ≥44, responsive 320→ultrawide.
