* Record action layer selections by name and show their targets
* Use document pixel format in grouped-layer regression
* Document the named layer action UI with a synthetic capture
Steps can be deleted and dragged into a new order, live while recording. Playing an action
while recording stores one named actions.play call, and nested playback stops on a child
failure, rejects cycles and goes at most 16 levels deep. Right-click an action to give it
F1-F12 (saved in preferences). View > Fit on Screen (Cmd+0), Zoom In/Out and 100% record and
replay. New actions.move command; actions.delete takes a step.

* Test separate render targets for canvas mip generation
* Read back canvas mip levels after full and partial uploads
* Gate the mip scratch-texture workaround to DX12
Creating a scratch texture and copying back per mip level on every edit cost about 3.8 ms
p50 for a 128x128 update (the PR's own Metal numbers). The corruption it works around is an
Intel DX12 driver fault, so only DX12 adapters take the scratch path now
(Resources::separate_mip_targets); every other backend renders straight into the level as
before, with main's timings. The readback test runs both paths.
