/* ============================================================
   pepbits assistant — the floating chat panel.
   Colours are the site's theme tokens with literal fallbacks, so every
   palette (including the dark theme preset in the header picker) styles
   it without knowing it exists. The panel (z-index 70) sits above the
   page content but below modals (home.css puts .modal and .skip-link
   at z-index 100).
