/* ============================================================
   YUBASync Link — hoja propia de la landing del integrador.

   REGLAS QUE SE SIGUIERON AQUÍ
   1. Cero tokens nuevos: color, tipografía, radios y sombras salen de
      `../styles.css`. Lo único propio es el prefijo `lk-` para no chocar con
      las clases de la home (que también carga `script.js` en esta página).
   2. El acento sale SIEMPRE de `var(--fam)` (violeta en esta familia). Si
      mañana la familia cambia de color, no se toca una sola regla de aquí.
   3. Público técnico: la jerarquía la marca la tipografía monoespaciada, no
      el color. Menos decoración, más contrato.
