/* MyCampus Web: VitePress-like styling.
 * Tokens follow the main site (docs/.vitepress/theme/themes.css):
 * --vp-c-bg, --vp-c-bg-alt, --vp-c-bg-soft, --vp-c-border, --vp-c-text-1/2/3,
 * --vp-c-brand-1/2/3, --vp-c-brand-soft and --accent. The Default theme
 * keeps the VitePress look (light, dark via prefers-color-scheme); the
 * other 11 themes set their own tokens. theme-init.js applies the saved
 * prefs before first paint, so there is no flash of the default theme.
