/*
  FINK invoicing app — plain/simple theme.

  This intentionally follows the STRUCTURE of fink-website's design system
  (documented in that project's notes: CSS custom properties in :root,
  Rajdhani/Exo 2/Inter font stack, Exo 2 as the Cyrillic-capable font)
  without copying its actual dark/red angular marketing look — this is a
  data-entry tool, not a marketing page, so the theme here is light,
  neutral, and plain. If FINK's real source files are made available
  later, these variables are the place to reconcile the two.
