Review follow-up: `effects/x/radius`, `effects/0` and `effects` name no
effect's field, but `list_binding` doesn't parse them, so the layer's
check took them for some other field and kept an inert binding. A key
under `effects` that names no effect's field is now refused as well.
`variable.bind` on a layer checked only the variable's type against the
field's scope, so `effects/0/refraction` on a drop shadow, or a binding on
an effect the layer doesn't have (`effects/9/radius`), was kept and did
nothing. An effect style already refuses both. The layer now uses the same
check: effect `i` must exist and have the field, and the field's type
comes from that effect. A binding an older file has on such a field still
does nothing, and still unbinds.
The previous fix made a local share's `link` follow the code shown, but its
top-level `url`, the session's WebSocket URL, still carried the edit token:
`collab.join {link: url}` from a view-only share joined with edit access and
the edit reached the host. The link layer now hands over the view way in as a
link and its URL (`SessionInfo::view`, a `WayIn`, in place of `view_link`), and
`collab.peers` gives a local share's `link` and `url` from the way in for the
code shown (`Live::invite`). Online shares are unchanged.
Regression test: `code_tests::a_local_view_share_s_link_and_url_only_let_people_look`
joins through the `link` and then the `url` over loopback; both are welcomed as
viewers whose edits never reach the host.

`collab.share {via: "local", access: "view"}` showed the view-only code but
gave the session's own invite link as `link`, and that link edits: whoever
joined through it could change the host's file. A local share's `link`, top
level and in `sessions`, is now the one that goes with the code shown, and it
follows `collab.share {access}`. Online shares keep the owner's own link there,
as before.
Regression test: `code_tests::a_local_view_share_s_link_only_lets_people_look`
joins through that link over loopback and is welcomed as a viewer whose edit
never reaches the host.

The session the app hosts for a local network share now has two secrets:
the edit code and a view-only code (same address and port, a 44-bit secret
of its own). Whoever joins with the view code is welcomed as a viewer: they
see every change and presence, the app makes the file read-only for them,
and the session refuses their batches, as a server does for view links.
Share > Local network offers Can edit / Can view before sharing starts (the
edit code then never shows) and while sharing. collab.share {via: "local",
access: "view"} does the same; share in collab.peers lists both codes and
links. There is still no comment code on the local network.
Next::Stop boxes its event: SessionInfo grew past clippy's
large_enum_variant threshold, and it only ever carries a status or an end.
Tests: loopback_tests::a_view_token_lets_people_look_and_not_edit,
code_tests::a_local_view_code_lets_people_look_and_not_edit,
live_share_tests::a_local_share_can_start_for_looking_only, and the local
share tests that asserted edit-only codes. Docs: collab-protocol.md,
collaboration-parity.md.
`proto.settings` took any string as the device ("Pixel Nonexistent", "iphone 16") and saved it in
the file: the presenter then drew no device frame while its picker showed the name as if it were
one. An unknown colour was already refused with the device's colours, but a typo in the device
went unnoticed, and an agent couldn't read the settings back (`proto.settings {}` answered
`{ok: true}`, and neither `inspect_document` nor `get_node` shows a page's prototype settings).
An unknown name, or a value that isn't a string, is now refused with every name the picker offers
("None", "Custom size" and the devices), and nothing changes. A known name is taken in any case and
with spaces around it, and stored as the picker spells it (`known_device`). Every call answers the
page's settings as they are after it (`settings_json`): device, background, rotation, the colour
shown, the screen as presented (null without a device), the custom size and responsive, beside the
`ok: true` it answered before; `proto.settings {}` reads them.
Test: `proto_present_tests::unknown_devices_are_refused_and_settings_read_back`. Docs: mcp.md,
prototyping-parity.md, ROADMAP.md.

A padding changed on both sides of a branch gave a conflict for every size and place auto
layout worked out from it: the component's, each instance's and their hugging parents' width
and height, each instance's layout, and every child's position (10 in a file with one instance,
138 with 15). The merge was refused until each had a side, yet the merged file laid itself out
again from the padding whatever they got. A `layout` conflict also took all auto layout fields
together, so a gap changed only on the branch was lost when main won the padding.
`merge::plan` now leaves out properties both sides changed to values both files work out for
themselves (`Plan::derived`): a hugging auto layout frame's or a filling child's size, text
sizing to its characters, an auto layout child's place (when both sides turn and scale it the
same way), and a value a layer in an instance has as its main's layer has it. Merging keeps the
file merged into's own value and normalising lays it out from the merged inputs.
`layout` and `childLayout` merge field by field: a field changed on one side (or the same way on
both) merges, and each field changed both ways is a conflict of its own (`Key::Field`,
`<id>/layout.padding`), written whole from the merged fields and each picked side's value. The
review shows it as "auto layout padding" with both sides' values ("8, 8, 8, 8").
Tests: `branch_tests::one_conflicting_auto_layout_edit_is_one_conflict` (the issue's file: one
conflict, either side laid out as if set directly), `auto_layout_fields_changed_one_way_survive_a_conflict`
(merge and update from main), `sizes_auto_layout_works_out_never_conflict`; the merge fuzz test
leaves worked-out values out of what each side must show. Docs: collaboration-parity.md, mcp.md,
ROADMAP.md.

A file imported from another app can hold library copies in its library
store with no record of the library they came from. On an instance of
one, the command took the local path and failed in selecting it with
"isn't on a page (it is a library component)", which says nothing about
what to do. It now says the copy has no link to its library and that
enabling the library reaches it.
Found on a real imported file, where copies of the same library set were
cached more than once and only one of them could be linked.

On an instance of a library component the command refused with "open
that file to edit it". The help center describes it opening the file that
holds the main ("Edit main components"), so it now does: the linked
library file opens in a tab, or its open tab comes to the front, on the
main's page with the main selected and zoomed to.
The library keeps the file's layer ids, so the copy's id map
(ImportedComponent::ids) leads from the local copy back to the exact
layer: a nested instance reaches its own main and a variant that variant.
The new tab takes the canvas size of the tab it came from. A tab still at
the default 1200x800 is refitted to the whole page on its first frame,
which would replace the zoom to the main.
A main deleted from the library file since it was published leaves the
file open with a note. A moved library file, a team library on a server
and a path off this computer are refused before anything opens; the last
uses the same check that guards library reads.
