/* ──────────────────────────────────────────────────────────────────
   BNE.LIVE — Tweaks panel CSS
   Pinned bottom-right runtime panel for theme/font/accent toggles.
   Loaded on BOTH the public site and the admin shell (the panel ships
   the same on both surfaces). Self-contained so it can't be broken by
   downstream stylesheets — every property is explicit, no token reads
   that might flip under .bne-light unexpectedly.

   options vanish into a white-on-white surface. */
