   The operating theater — rx no.013, the volatile anesthetic.
   A compact illustrated edition: one painted room with four registered
   lighting plates, thin editorial feature rows, a window study and the
   Steam ↔ native-UI diagram. Colors are oklch tokens; hex survives only
   inside data-URI SVG.
