/* =========================================================================
 * KHY AI Frontend — design tokens & Element Plus theming
 *
 * Token-driven, dual-theme (light / dark). The design language is adapted
 * from new-api's shadcn/oklch palette but expressed as hex/rgb so it can map
 * cleanly onto Element Plus CSS variables.
 *
 * Theme switching is driven by the `dark` class on <html> (see
 * src/composables/useTheme.js). Element Plus dark css-vars are imported in
 * main.js; the overrides below re-point both EP and our --khy-* tokens so the
 * whole surface reacts to a single class toggle.
