/* mktn.es · Ficha de caso (plantilla v2, direcciones G22 a G25 de Claude Design)
   Una sola hoja para las 19 fichas. El color del proyecto entra con tres variables en <main class="case">:
   --cbg (fondo de la cabecera), --cink (tinta) y --cacc (acento para texto, ya corregido a 4,5:1).
   Sin ellas, la ficha usa el neutro #E9E7E1 / #161616 / #1F3A30.
   Por contenido (el build decide, nada editorial): .has-peek en <main> cuando la primera captura de escritorio abre
   la primera sección (asoma de la cabecera); .is-prin / .is-list / .is-lane en cada sección según lo que contiene.
   Variables por ficha: --ch (caracteres de la línea más larga del h1), --vl (caracteres del valor de métrica más largo)
   y --n (número de métricas) en .case-hero-l, .case-ms.                                                             */
