  # Upstream ships dozens of dangling symlinks (icons aliased across sizes
  # that don't all exist) — same class of minor packaging bug as
  # azure-glassy-dark-icons. Harmless: GTK/Qt icon lookup falls through to
  # the theme's own Inherits= chain (breeze-dark, Adwaita, hicolor) for those.

  # index.theme's Directories= lists panel/16@2, panel/22@2, panel/24@2 (with
  # Scale=2), but the actual on-disk dirs are named 16@2x/22@2x/24@2x (the
  # correct freedesktop-spec suffix) — an upstream index.theme typo. That
  # mismatch makes `gtk-update-icon-cache` refuse to emit ANY cache at all
  # (exits 1, "The generated cache was invalid"), so unlike the other vendored
  # themes here, this one ships with no icon-theme.cache and relies on GTK's
  # live directory-scan lookup instead — functionally fine, just not
  # cache-accelerated. gtk3's default postFixup hook (dropIconThemeCache)
  # would strip a cache anyway, so there's nothing to opt out of.
