/* ===========================================================================
   GODOT LMBAKE VIEWER — the tool's own interface.

   Same rules as bitmap-font-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 second palette that ignores it.

   The exceptions are the two canvases. A canvas cannot read a custom property,
   so the handful of colours the probe map and the histogram need are declared
   once as --lm-* here, given a light-mode value alongside, and read back out in
   JS (readPalette() in lmbake-viewer.js) whenever the theme changes.

   The probe map's own background stays dark in both themes on purpose: it is
   showing light in a room, and a probe reading near black has to look near
   black rather than being washed out by a pale panel behind it.
