/* ==========================================================================
   Terms.Law — Pillar Component Library (pillar.css)
   Vanilla-CSS component system powering pillar articles and the 20 top AI-cited
   page upgrades. No build step. Paired with pillar.js.

   Tokens are prefixed `--pillar-*` to avoid colliding with legacy per-page vars.
   Reuses canonical site vars (--color-primary, --color-text, --font-family)
   from CLAUDE.md §6 when present; falls back otherwise.
