PSD Import
Bring a layered Photoshop design in as components — and send it back out.
The manifest, and Export PSD.
The manifest written at import time is what makes the round trip possible: it maps every Photoshop layer path to the node or group it became, along with its bounds and opacity. Export PSD in the Files panel reads it back and rebuilds a .psd from the current scene.
That means a designer can adjust the layout in Photoshop, re-import, and keep the structure recognisable — rather than starting from a flat picture.
