   Music Lab · Piano virtual (/herramientas/piano)
   On top of music-lab.css. The instrument keeps its own dark palette in
   both themes: a stage, not a page. Everything about the keys is measured
   in white keys: --x (the view's offset, white keys) and --v (white keys
   in view), set on the article by the bundle; each key carries --l (left)
   and --w (width) from the server, and the keys and the strip are placed
   as percentages of the stage, so --v keys fill it exactly. --ww (one
   white key, px) is kept for the bundle's gestures.
