/* Section R (#roots): the stock Plasma 6 panel and Krema on one wallpaper,
   split by a draggable handle.

   The scene is drawn at 1:1 CSS px in "logical" desktop pixels, like a
   Plasma session at scale 1 (or 2 on HiDPI screens). Below 920 px of width
   js/panel.js scales the whole scene down instead of squeezing the panel.

   The left half reproduces a capture of the default Plasma 6.7 panel
   (Breeze Dark, Fedora 44, 1280x720 at scale 1 and 2; branding/panel-ref).
   Every size, offset and colour in the .pp block below was measured from
   that capture. Keep it Breeze: none of it follows the site palette. */
