   DocGen — shadcn-flavoured design system (plain CSS, no build step).
   Mirrors shadcn/ui's token model: HSL design tokens on :root, a .dark theme,
   --radius, and component classes (button / card / input / badge / table).
   The EJS views keep their semantic class names; this file gives them the look.
