/*
  Viridian Interactive — site styles (local preview scaffold, 2026-11-13).

  Token names and the HSL-triplet format follow the [Viridian] token contract in
  viridian-brand/visual/colors.md §1. That file has NO company-level palette
  (only Compass and Harbor product palettes), so the VALUES below are
  PROVISIONAL placeholders, not brand decisions. Replace them when the founder
  sets a company palette.
  Fonts: system stack, because no typeface is decided (typography.md).
