 * Gradespace Tutor: the student and staff portals (Pro). A page of their own:
 * the theme's stylesheets aren't loaded, only its colours and fonts (theme.json
 * presets, through Core's --gsc-* tokens when the theme maps them for the
 * portal) and anything a theme adds on the gstu_portal_enqueue hook.
 *
 * Colours are only ever used in pairs the Tutor theme's palettes are checked
 * for (ink, muted on surface and page; on-accent on accent), so text keeps
 * 4.5:1 in every design and palette, the dark ones too.
