/* ===========================================================================
   VIDEO COMPRESSOR — the tool's own interface.

   Same rules as background-remover-styling.css next door: every colour is a
   site token or derived from one, so the panel follows the reader's theme
   instead of carrying a palette of its own. --vc-* below are only for values
   that stay fixed regardless of theme.

   Controls (.vc-select / .vc-range / .vc-label / .vc-section / .vc-hint) copy
   the bitmap font editor's field idiom rather than the plain radio pills
   background-remover-styling.css uses, because this tool has a full settings
   grid rather than one or two choices — same reasoning as that file gives for
   keeping its own copy of the button styling rather than sharing a class.
