   ROADMAP — editor and viewer (roadmap.html)
   Visual language inspired by PrimeNG's Aura theme: zinc surfaces, emerald primary,
   6px controls, 12px panels, tinted severity tags, soft focus rings.

   Theme rule: dark/light only swaps COLOUR tokens. Sizes, spacing, radii and shadow
   geometry are defined once, in :root.
