/* ChaChing Panel 2 — hoja de estilos única del sitio.
 *
 * Lenguaje: página de producto al estilo Apple. Clara por defecto, con secciones
 * negras de composición (no de preferencia del usuario). Un objeto pequeño mostrado
 * grande, solo, sobre nada, con una frase corta debajo. Sin sombras, sin degradados,
 * sin tarjetas con icono, sin modo oscuro del usuario.
 *
 * Referencia de decisiones: productos/chachingpanel/web-apple-analisis/04-lenguaje-de-diseno.md
 * Breakpoints: 1068 y 734 (los de apple.com). Tokens abajo; las secciones oscuras
 * redefinen el ROL de cada token con .is-dark, no el token.
