/*
  Shared design tokens for the Bushwick Daily grocery price index visualizations.
  Matches bushwickdaily.com's dark theme (measured from the live site, July 2026):
  page background #0a0a0a, Satoshi font, white headlines, gray body text, yellow UI accent.
  Data colors are a separate, colorblind-validated set — kept distinct from the
  site's yellow so chart data never looks like a clickable link/CTA.
