/*
 * VSMS theme, built on IBM's Carbon Design System:
 *   - colour: Carbon "g10" theme for light mode, "g100" for dark mode
 *   - type: IBM Plex Sans / Plex Mono, Carbon productive type scale
 *   - motion: Carbon duration and easing tokens (productive for UI, expressive for page entrances)
 *   - shape: square corners, hairline dividers, no drop shadows on tiles (Carbon "layers")
 *
 * Token names stay VSMS-specific (--surface, --text-2 ...) and are mapped onto Django admin's
 * variables, so every page (dashboard, lists, forms) follows the same palette.
 *
 * Dark mode follows the OS setting unless the user picks light/dark with the theme toggle
 * (html[data-theme]), exactly like Django admin itself.
