/* Shared base stylesheet for every site.
 *
 * Token names match the Device Lifespan stylesheet so components move between
 * sites unchanged. A site restyles itself by overriding tokens in its own CSS,
 * loaded after this file - never by editing this one.
 *
 * Dark mode is declared twice: the media query follows the OS, and the
 * data-theme scope lets the toggle win in both directions. */
