Restrict spotlightOpacity to spotlight regions.
A non-spotlight region with a stored finite spotlightOpacity keeps that field. For example, a region changed from spotlight to blur normalizes with spotlightOpacity still set. Check region.type === "spotlight" before preserving or defaulting the value.

- spotlightOpacity: isFiniteNumber(region.spotlightOpacity)
- ? clamp(
- region.spotlightOpacity,
- MIN_SPOTLIGHT_OPACITY,
- MAX_SPOTLIGHT_OPACITY,

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Exclude disabled annotations from the preview visibility filter.
handleAnnotationTypeChange preserves disabled when a spotlight changes to another annotation type. The preview filter only checks the time range, so the converted annotation can remain visible in AnnotationOverlay. Both export paths exclude disabled annotations, which creates preview/export differences.
Update the shared visibility helper. Keep persistence unchanged.
export function isAnnotationActiveAtTime(
- annotation: Pick<AnnotationRegion, "startMs" | "endMs">,
+ annotation: Pick<AnnotationRegion, "startMs" | "endMs" | "disabled">,
timeMs: number,
): boolean {
return (
+ annotation.disabled !== true &&
Number.isFinite(annotation.startMs) &&
Number.isFinite(annotation.endMs) &&
timeMs >= annotation.startMs &&
timeMs <= annotation.endMs
);

Description
Adds a new Spotlight annotation type that dims the video outside one or more highlighted areas. This is the "highlight" mask commonly used in product demos, and it complements the existing Blur annotation.
spotlightannotation tab next to Blursrc/lib/spotlight/spotlightMask.ts.recordlyprojects; older projects load unchangedMotivation
Recordly can blur sensitive areas but has no way to draw attention to a specific area of the screen. A spotlight is one of the most common effects in demo and tutorial videos (for example Screen Studio's "Highlight" mask), and today it has to be done in a separate editor.

Also fixes an existing preview bug (separate commit): when the editor is paused inside a zoom region and the preview layout refreshes (for example after selecting an annotation or resizing the panel), the Pixi camera was reset to identity but the paused ticker never re-applied the zoom. The annotation overlay kept its zoomed transform, so annotations dragged in that state were saved with wrong coordinates and drifted once playback resumed. This affected Blur and every other annotation type, not just Spotlight. The fix requests a paused-frame refresh right after the camera reset.
