/* pianoroll.css — styles for the piano-roll editor.

   Colours are read from CSS variables with built-in fallbacks:
   var(--accent, #5ad1ff). Drop this file into any page and it looks right;
   drop it into an app that already defines --accent, --line and friends and
   the editor picks up that theme instead. Never define those variables here,
   or a host application's theme would be overridden.

   Every class is prefixed pr- to avoid clashes. */
