 * SIGNATURE EDITOR — brand skin (owner's Figma language, Aug 25).
 * Loads LAST on index.html only. The owner's editor frames are deliberately
 * incomplete shells; per NEXT-TASKS the agent applies the brand language over
 * the EXISTING working editor. Kill-the-blue phase 3: token remap retires
 * every var()-driven blue, the rules below retire the literals.
 * The rendered signature inside #mockWrap is untouched — it carries its own
 * inline styles (email doctrine) and must keep looking like real output.
