ThemeService

class

Owns the IDE's color theme.

The theme is entirely self-contained: on start it injects its token stylesheet and applies the saved (or system) theme; on stop it removes the stylesheet and restores Monaco. Everything is scoped to the ide-root host and IDE overlay panels, so the host application's own theme is never read or written and the IDE leaves no trace when it unmounts.
