/* ACP Paint Protection — brand tokens.
   Every value here was MEASURED off the supplied logo artwork, not chosen.
   Contrast ratios are computed, not estimated. See BRAND-KIT.md for method.

   The one rule that governs everything below:
   ACP Gold is 11.02:1 on black and 1.91:1 on white. It is a DARK-GROUND
   colour. Build dark surfaces and the palette works with no substitutions;
   build light surfaces and every brand colour needs its deep counterpart. */
