/* Chispa · La célula · componentes del libro (clases 2–6, laboratorio, glosario)
   Se carga después de classroom.css y usa sus tokens. Ronda 2 de diseño:
   - El atlas de organelos comparte el aspecto de .part-buttons (punto y color --part).
   - Las etapas del comparador, el ciclo y la mitosis marcan la actual igual que
     el recorrido de la proteína (.process-stops): rosa Chispa.
   - Con panel fijo en escritorio, laboratorio y atlas caben sobre el pie fijo. */
