/* ═══════════════════════════════════════════════════════════════════
   Mr McKenzie — styles for the shared editor and settings panel.

   A real stylesheet rather than CSS injected from JavaScript, because
   the SQL app sends a strict Content-Security-Policy (style-src 'self',
   no 'unsafe-inline'). A <style> element created in script counts as an
   inline style and is dropped silently — the element exists with zero
   rules, the overlay falls back into normal flow, and the code appears
   twice. Served from the same origin, this is allowed as-is, and the
   policy stays strict.
