/**
 * Kprichos Chat — Estilos.
 *
 * DISEÑO
 *   Paleta inspirada en los colores de la tienda (cocoa, beige, negro).
 *   Sello visual: la cinta métrica bajo la cabecera, porque aquí todo gira en torno a la talla.
 *   Sin fuentes externas: pila tipográfica del sistema (cero peticiones extra, cero impacto SEO).
 *
 * PERSONALIZACIÓN
 *   El color principal llega desde Ajustes como variables CSS (--kpc-accent, --kpc-accent-dark,
 *   --kpc-accent-soft, --kpc-on-accent). Los tokens de abajo se cambian en un único sitio.
 *
 * MAPA: 1. Tokens · 2. Reset defensivo · 3. Lanzador · 4. Panel · 5. Cabecera · 6. Mensajes
 *       7. Sugerencias · 8. Formulario · 9. Móvil · 10. Movimiento reducido e impresión · 11. Tarjetas de compra · 12. Club · 13. Invitación proactiva
