/* ============================================================================
   JIGNASA CLUB — Design Tokens
   Re-themed to match design-system/DESIGN-SYSTEM.md (extracted from the
   HTML/ prototypes): a warm, hand-crafted, editorial system — off-white
   paper ground, serif display+body pairing, teal-to-green brand gradient,
   organic radii. Dark mode is authored independently, not an auto-invert.

   This file keeps the SAME custom-property names that base.css, site.css,
   components.css and admin.css already consume (--bg, --text, --accent-strong,
   --radius-sm, --fs-h1, etc.) — only the values changed. That's deliberate:
   it re-themes the whole app through one file instead of touching every
   selector that references a token.
