/* ============================================================
   CAPTIA Tech — páginas de caso (es/casos/, en/cases/, pt/casos/)
   Escena fijada al hacer scroll («a mano» frente a «automatizado») y
   calculadora de horas recuperadas. Lógica en assets/js/caso.js.
   Hoja aparte, como servicio.css: styles.css va immutable a un año y subir su
   ?v= obliga a tocar todas las páginas. Prefijo cs- para no chocar con las
   clases genéricas (.doc, .row, .status, .btn...).
   Sin JS o con reduced-motion no hay escena: se ve la cabecera de cada columna
   y la tabla estática con los mismos pasos (html sin la clase .cs-motion).
