/* ============================================================
   SKETCH PAD

   The paper itself is deliberately theme-independent (always light) — see
   the header comment in public/js/notes/sketch-pad.js for why. Everything
   around it follows the app theme as normal, and in Ember/Dark the paper
   gets a soft ring so it reads as a sheet laid on the surface rather than
   a blown-out rectangle.
