/* ================================================================
   CIRCLE CHIROPRACTIC — kit tokens, verbatim.
   Source: reference/kits/circle/tokens/{fonts,colors,typography,
   spacing,effects,base}.css. ZERO invented values.
   Deltas (logged in /circle-kit/guide/ §Token Fidelity Audit):
   1. @font-face src paths rewritten to this site's assets/fonts/
      (same kit woff2 files, byte-identical copies).
   2. ONE addition: @font-face for "Newsreader" italic — the kit
      ships assets/fonts/newsreader-italic.woff2 and uses the face
      throughout ui_kits/website/home-explorations-v4.css, but
      tokens/fonts.css never declares it. Declared here; no new
      family invented (file + usage are both kit-supplied).
