/* ============================================================================
   Design Pack · compat/filedrop.css
   Maps FileDrop's existing token names onto the pack, so FileDrop can adopt
   tokens.css with ZERO visual change and migrate page by page afterwards.

     <link rel="stylesheet" href="/design-pack/tokens.css">
     <link rel="stylesheet" href="/design-pack/compat/filedrop.css">
     <style> ...the page's own CSS, which still wins... </style>

   Note --surface-1 and --ink-1: FileDrop uses these 13 times across nav.js,
   admin.html and filevault-history.html and declares them NOWHERE, so every
   use silently falls back. Mapping them here fixes that as a side effect of
   adoption. See interface-design-system.md §17.3, defect 1.

   DELETE THIS FILE when FileDrop has finished migrating to the --rx-* names.

     the state green — the nav pills that once did were moved to literals when
     v0.4.0 burned them. So the alias follows the majority; audit-log.html and
     index.html carry a one-line local binding to var(--rx-ink) instead. The
