WorkspaceGeek · Host theme lab
Set msclient_key once on the host canvas, then drop a bare
<wsg-portal>. Pick a simulated host palette; this lab forces
host-inherit styling so the widget picks up canvas colors.
Every preset ships a light and a dark palette; the Light / Dark toggle
switches the simulated host page independently of which preset is
selected. Lab chrome follows system light/dark.
Temporary for this page only — widget inherits palette & fonts from the canvas. Lab chrome is separate.
