   LSC Billing — base stylesheet.

   Ported VERBATIM from the Electron app's index.html <style> block, with two
   deliberate exceptions, both visually inert in a browser:
     • the base64 @font-face blobs became real files in ../fonts/ (below);
     • -webkit-app-region declarations were dropped (Electron-only).

   The Desktop Preservation Law applies: do not edit rules in this file. The
   >=1100px layout must stay pixel-identical to the desktop app. Responsive and
   accessibility work is additive, in files appended after this one.
