/* Lillie Coit's — colour. FOUR colours, and only four.
   NAMES ARE PLACEHOLDERS: cream, gold, red, green. The house will name them
   properly later; until then do not invent descriptive names for them.
   Every value is lifted verbatim from LILLIE COITS - Color Schedule.pdf
   (Pantone / Sherwin-Williams cross-referenced). Nothing here was invented.
   Locked August 2026. The other twelve colours in that PDF are an interior
   paint schedule, not a brand palette — they are deliberately NOT tokens. */
