   COLOR VARIABLES — drop your extended palette hex values in

   so sections are visually distinguishable before you fill in
   real colors. Grouped to match a "family + accents" palette
   structure: a primary ramp, a secondary/CTA ramp, a neutral
   ramp, and a set of standalone accent colors for anywhere you
   need several mutually-distinct colors side by side (cards,
   category pills, chart-style elements).
