   components.css — capa de clases ds-* (sin framework de JS)
   Requiere themes.css cargado antes.
   Consume SOLO variables semánticas (--ds-surface-*, --ds-text-*, ...),
   de escala (--ds-space-*, --ds-radius-*, ...) y de componente
   (--ds-control-*, --ds-table-*, --ds-target-min). Nunca --ds-p-*.
   Estados: se expresan con atributos nativos/ARIA cuando existen
   (:disabled, [readonly], [aria-invalid="true"], [aria-selected],
   [aria-current], [aria-expanded], [aria-busy]) y con .is-* cuando no.
