Paste (also without formatting) goes to the centre of the view
(edit.paste {center}); Paste in Front/Back with nothing selected go to
the top/bottom of the current layer, in order; Paste on All Artboards
keeps the objects' offset to the artboard they were copied from.
layer.pasteRemembersLayers {on?} (document flag paste_remembers_layers,
saved, document.inspect) pastes objects back into the layers they came
from by name, making missing ones; the Layers panel now has its menu
with the layer commands and the check item. The Paste menu items are
enabled while the system clipboard holds SVG (looked at once per frame
at most, a few times a second).

Clicking a Layers panel target circle runs `layer.target {id}`: a layer gets its art
selected and becomes the target (`Selection.target`) of the appearance, effect,
transparency and opacity-mask commands, which then edit the layer itself; the
Appearance panel lists it. Dragging a circle onto another runs
`appearance.transfer {source, target, copy?}` (Alt copies), dropping it on the trash
clears it. Filled dots also mark groups and layers with fills of their own, masked
objects get a dashed underline, and while an opacity mask is edited the panel lists
only an `<Opacity Mask>` entry and the tab says so.

layer.clippingMask.toggle {id?} -> {clip}: the top object of the current
layer (or of the one selected group, or of `id`) becomes the clipping path,
unpainted and moved to the bottom so art added later is clipped too; pressing
the button again releases the mask and leaves the path unpainted. One undo
step. The Layers panel button runs it and underlines clipping-path names.
Model: NodeKind::Layer.clip (skipped when false). Clipped layers render, hit
test, bound, and export to SVG and PDF like clip groups (Node::clips /
set_clips); the clip-path helpers are shared with Make/Release Clipping Mask.
