/**
|
|
* Lazily load the editor-only side effects, keeping them out of the
|
|
* flag-off classroom/playback bundle:
|
|
* 1. `editor-fonts` — ~23 @fontsource font-face tables the slide font
|
|
* picker needs (CSS side effect).
|
|
* 2. `surfaces/slide` + `surfaces/quiz` — register their SceneEditorSurfaces
|
|
* into `sceneEditorRegistry` so EditShell can resolve them (otherwise it
|
|
* falls back to NOOP_SURFACE, i.e. a read-only flash).
|
|
*
|
|
* Called from the Pro Switch handler BEFORE flipping into edit mode, so
|
|
* the dynamic chunk is already downloaded/registered by the time the
|
|
* edit chrome mounts and animates in — no mid-animation "content pops in"
|
|
* jank, and the slide surface is registered before EditShell reads the
|
|
* registry. The promise is cached so repeated toggles and any belt-and-
|
|
* suspenders caller share one in-flight import.
