/* ===== Nidarshana Vedh Vastu: design system =====
   Warm sandstone, terracotta and deep brown. Every colour is a custom property,
   defined for both themes. Contrast for the text pairs is checked by
   scripts/nv_vastu/check_contrast.py (WCAG AA, 4.5:1).
   The names --parchment-*, --ink* and --gold-ink at the bottom of each theme
   block exist only so the email step (nv-gate.js, copied unchanged from the
   other sites) picks up this site's colours. */
