/* ──────────────────────────────────────────────────────────────────
 *  Nano CMS - NEON blog theme (theme-neon.css)
 *
 *  Re-skins the demo blog to match the "Neon Streets" marketing site
 *  (digitalfracture.co.uk/nano-cms). Self-contained: carries the
 *  self-hosted fonts, the shared site chrome (marquee / header / footer),
 *  and the blog re-skin (it overrides the --nano-color-* custom properties
 *  that nano.css exposes, plus a handful of flourish rules).
 *
 *  EVERYTHING visual is gated behind html[data-theme="neon"] (the default).
 *  Toggling to data-theme="default" hides the chrome and falls back to the
 *  stock nano.css look that ships with the product. The .nano-theme-toggle
 *  button is styled for BOTH states so it is always usable.
 * ────────────────────────────────────────────────────────────────── */
