   Source video is a Pexels asset that ships in colour (blue helix);
   we transcode it to grayscale (`ffmpeg -vf format=gray,format=yuv420p`)
   so the asset itself is already neutral. With a grayscale source the
   LUMINOSITY blend mode is redundant — straight opacity does the job
   and behaves predictably in both themes. For light mode we invert
