/* Theme variables: light is the default, dark follows the system
   (prefers-color-scheme), and html.dark / html.light override the
   system when the user toggles the theme button. The html rules
   must come after the media query and must stay in sync with it —
   otherwise a manual toggle would not beat the system choice.
   Photos, face boxes, and the play stage are not themed: a photo
   must look like the photo, and the stage is already dark. */
