   DEADLANE — Operator's Manual (manual.html, generated by codex/build.py)
   Visual system from the operator-manual UI kit (design-tokens.json):
   charcoal surfaces, thin cool-gray borders, clipped corners, orange
   for "where you are" and primary actions. Selected state is a left
   rail plus label — never color alone. Element hues match the game's
   card accents and are used only on element markers.
