/* Theme override for the self-hosted PDF.js viewer (see viewer.html).
   PDF.js's own stylesheet defines every color via CSS light-dark(), keyed off
   the `color-scheme` property. Forcing color-scheme to dark here switches the
   whole viewer to PDF.js's native dark theme, unconditionally (regardless of
   the visitor's OS/browser preference) — no custom colors invented, this is
   just "the dark half" of PDF.js's own built-in palette. */
