     Achievement Education — 2026 brand palette
     Marigold (primary accent) · Deep Navy (anchor) · Warm Ink (neutral),
     on a soft Paper background. Evolved 1:1 from the original palette:
       Gold Rush  → Marigold      (warmer, less neon)
       Blue Dianne → Deep Navy    (deeper, true navy)
       Rich Grey  → Warm Ink      (warmed neutral)
     The original variable NAMES are kept as aliases, so every existing rule,
     layout, and component is untouched — only the color values change.
