   bulb-wall.css  —  💡 The Idea Wall (business-idea generator) styling (.bwl-*)
   A bare bulb hangs over a red brick wall in the dark; it flickers, catches, and
   floods the wall with warm light — revealing the idea on the brick.
   Self-contained. Warm amber accent.
   ⚠️ scene coords/rays match bulb-wall-engine.js (buildRays uses cx170 cy98).
