   Ages Productions — brand foundation, extracted for the LED Wall property.

   Source of truth: the Ages Productions design system doc
   (ages.productions repo → _internal/Ages Productions Design System.html).
   Values here are copied verbatim from that system's styles.css so the two
   properties stay visually related. Do not invent new colours or type here —
   if this project needs a token the brand doesn't have, add it under the
   "LED-specific" block at the bottom and say why.

   This file is deliberately standalone: the LED project must not depend on the
   Ages repo at build or run time.
