Returns

string: Stable collector ID.

snapshot()

protected function snapshot(): PHPForge\Debug\Panel\Asset\AssetSnapshot|null

Captures every application asset bundle registered during the request into the snapshot consumed by the detail view. The debug toolbar’s own bundle is excluded because it is infrastructure rather than application content.
