/* PDFAccess UI
   ---------------------------------------------------------------------------
   Deliberately dependency-free: no CDN fonts, no external stylesheets, no web
   analytics. All visual assets are served with the app; document processing
   stays on the configured server. System fonts avoid third-party requests.

   The interface is also the product's own audience: real focus rings, state
   carried by words as well as colour, contrast held above 4.5:1, and every
   animation switched off under prefers-reduced-motion.
