v1.6.1

Patch Changes

• 5351c16: Themed render documents now declare a CSS color-scheme matching the requested
  theme, so user-agent-rendered surfaces (scrollbars, default form-control and
  <button> chrome) follow the theme instead of rendering in their light defaults.
  Previously a dark-themed preview kept light user-agent controls — most visibly a
  bare <button> showing the light ButtonFace background — which skewed dark
  snapshots and produced misleading color-contrast results against light control
  surfaces. The client keeps the color scheme matched across in-place theme swaps.
