/* Sterna GUI — refined visual system (GUI-VIS-*).
   A softer evolution of the original evryg tokens: same brand palette and
   signal-colour discipline, but rounded surfaces, layered elevation instead of
   hard 1px boxes, a calmer type scale, and more generous spacing. Class
   contracts are unchanged so the JS keeps working. */
