Filip StrajnarandClaude Opus 5.5 10df192b01 M9: a share on every interface links to an address others reach
A session hosted with `bind` 0.0.0.0 (or ::) kept listening on every
interface but put 0.0.0.0 in its edit and view links, URLs, join codes
and shown address, which nobody can connect to. They now name this
machine's local network address of the listener's family (loopback
without one), on the same port.

Oleksii Sukholita 3d41394bfc M3: glass's docs say which centre splay bends away from and where a shape gets no core
Splay bends away from the centre of the layer's bounds, as the reference
tool's does: on a ring or an L that centre lies outside the shape, so an
inner edge bends towards the hole. Checked side by side on a ring and an
L at Splay 0% and 100%. The module doc still said splay 0 bends along the
edge's normal; it bends towards the core since #1889.

`MAX_SHAPE_PX` now says it is 4M px on the desktop and 1M on the web, and
that a bigger shape gets no core, so a large glass text or vector can bend
differently once zoomed into, in a 2× export, or on the web.

Docs only.

Oleksii Sukholita 43403b3fed M8: glass takes one sample where its colours split under 1/256 px
The dispersion window samples the backdrop 18 times a pixel wherever the
curve bends it, even where the move is so short that the channels split
by a sliver of a pixel. Under 1/256 px every step lies within that of
the moved point, so one sample is within one level (of 255) of the window
over any backdrop, the hardest being 1 px columns of black and white or
of white and nothing. Those pixels now take one sample.

A larger split doesn't qualify: at 1/4 px one sample would move red and
blue by 1/8 px, up to 32 levels across a hard edge.

Trevor BrownandClaude Fable 5.1 36b728304b Minimize: a held press keeps its page point when the canvas moves, not only when it narrows (#2051)
While a press that went down on the canvas is held, the view centre now follows the canvas rect's own move as well as its size change, so a still pointer keeps its page point when the left sidebar or rail appears mid-press.

Zinadin Zidan 8842019aa4 Styles: the style and variable pickers grow back to their full height (#2043)
egui lays an area out inside the size it had on the previous frame, and a
scroll area shrinks to fit its content, so once a search or a short list
had made the style or variable picker small, it stayed small, also on the
next open. Both now offer their content the screen's height on every
frame. Their lists still stop at their own caps, and placement keeps them
on screen.

Filip StrajnarandClaude Opus 5.5 b779e46d47 M9: a local view-only share's url is the view URL, not the edit URL
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.

Trevor BrownandClaude Fable 5.1 5d21ca8791 Minimize: a click that shows the right sidebar no longer moves the frame it selects (#2051)
The view keeps its centre when the canvas is resized, so the right panel appearing (minimized UI, on the press that selects) shifted the pointer's page point by half the width over the zoom and the move handling took it as a drag. While a button that went down on the canvas is held, a resize now keeps the top-left instead.

Filip StrajnarandClaude Opus 5.5 a05201e21f M9: a local view-only share's link is the view link, not the edit link
`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.

Filip Strajnar a2be6632eb M9: share a file on the local network read-only, with a view-only code
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,

Denis GomesandClaude Opus 5.5 6a31ea7360 M3: Go to main component names a library copy with no link
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.

Denis GomesandClaude Opus 5.5 bea214ebb0 M7: decode a clipboard PNG before pasting it
with_pixel_size read only the PNG's header, so a PNG with a whole IHDR and
a cut-off body passed as the one to paste. Since #1724 image.place refuses
it as damaged, and nothing was pasted: the decoded clipboard image, which
paste falls back to for an unreadable PNG, was never tried. The PNG is now
decoded in full before it is accepted, so the paste falls back as it does
for any other unreadable PNG. The zero-size and pixel-count checks run
ahead of that decode, so an image past the limit is refused before it is
decoded.

Raised by CodeRabbit on #1360 after the merge.

Denis GomesandClaude Opus 5.5 76af4e3f43 M3: Go to main component opens the library file of a library component
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.

8eb0b87646 M3: glass bends towards its core, and rounded rectangles work it out in closed form (#1889)
* M3: glass bends with the reference tool's thick-lens profile and splits its colours over 8 steps (#1885)

The backdrop bends most a 1-unit bevel in from the edge, falls off as the
3.5th power of the way out of the curve to nothing `depth` further in, and
moves a fifth as much on the bevel itself (it fell off as the square of the
way in from the very edge). Dispersion samples each channel at 8 steps along
the bend with a triangular window, red moving furthest and blue least (it was
three samples, blue furthest), as far apart as the reference tool's: at 100%
red and blue move 0.16 of the bend apart (`Glass::DISPERSION_SPREAD`).
`Glass::max_bend` bounds red's furthest step, so the backdrop read around a
pane covers every sample, and the field margin covers the bevel.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: glass's bend stays within `max_bend`, checked on a single bright pixel too (#1885)

Review follow-up: the bend reaches `depth` × `refraction` a bevel in from
the edge, so `Glass::max_bend` drops its 0.999 and bounds it, as a test now
checks for several refractions. A single white pixel on black pins the
dispersion's triangular window, which a ramp and a flat backdrop can't tell
from one centred sample. The parity assessment records the bend, the
dispersion and how they were measured against the reference tool.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: glass's light is a line on its bevel, and splay turns the bend towards the centre (#1885)

The light is a line on the 1-unit bevel added to the backdrop, as the
reference tool's: fully where the edge faces the light, none below 0.35 of
facing it and 0.6 as much on the opposite side, with a faint gradient across
the curve, 5% darker facing the light and lighter opposite. It was a glow
mixed towards white, as deep as `splay` made it, so `light_reach` goes.

`splay` turns the bend from along the edge's normal towards the way away
from the layer's centre, and no longer widens the light: files with a splay
above 0 look different. The direction to the centre is worked out in the
shape's own frame (`own_frame`, shared with the field cache), so cut renders
match the whole one byte for byte.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: glass bends towards its core, and rounded rectangles work it out in closed form (#1885)

The backdrop bends towards the glass's core, the shape shrunk by `depth`
and the bevel, instead of along the smoothed edge normal: round a sharp
corner the bend turns smoothly instead of meeting along the diagonal, and a
part thinner than twice that (a capsule, a letter's stroke) bends across
itself towards its own middle, pixels about as deep as any within 2 px. The
fields keep a bend direction beside the normal (an exact feature transform
from the core, box-blurred once), their key includes the core's depth, and
their margin covers the core.

Rectangles, frames, components, instances and sections whose corners aren't
smoothed, under a rotation, flip and even scale, work their glass out in
closed form (`AnalyticRect`): signed distance, the light's normal (corners
rounded to at least the bevel) and the bend direction (corners rounded to
the core) per pixel, in the layer's own frame, with nothing to rasterise,
transform or keep. A zoom frame draws in 40 ms instead of 54 and a resize
frame in 46 instead of 67 (`glass_render_timings`, release, 2×).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: cut renders of glass match with splay turning a dispersed bend (#1885)

Review follow-up: the cut-versus-whole test had splay only on looks without
refraction, so no turned bend reached the dispersion. A look with splay 1 and
the default bend and dispersion now renders the same however it is cut. The
parity assessment records the light on the bevel and splay's new meaning.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M8: a glass too big to keep bends along its normals, and the core's fields take less memory (#1885)

Review follow-up: a shape that doesn't use the closed form and whose whole
window at the zoom, with the core's margin, would pass `MAX_SHAPE_PX`
(a large vector, text or smoothed rectangle, or a deep glass far zoomed in)
bends along its edge normals instead of working out a core, with the plain
margin. The choice depends on the shape and the zoom alone, so every band and
patch of a render agrees, and no render works out a core over more pixels
than a kept shape holds. The core's feature transform keeps `u32` indices
(16 bytes a pixel) and drops its maxima and core before making the
directions.

The edge normals are box-blurred twice again and the bend directions once,
as their docs say: the two were swapped.

The parity assessment records the bend towards the core and the closed form.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: glass's flat inside skips the bend's curve, and full dispersion stays within `max_bend` (#1885)

Review follow-up: `bend_at` returns 0 straight away past `depth` + the
bevel, where the curve and the bevel's easing are both 0, instead of
working out a power of 0 for every pixel of a pane's flat inside. A test
moves one white pixel along a row under every bend of the profile at full
dispersion and checks that no channel ever reads it further out than
`Glass::max_bend`, which sizes the backdrop read around a pane.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M3: glass's light shows over a transparent backdrop, and its flat inside skips the light (#1885)

Review follow-up: the light was added to the backdrop's colour and then
clamped to the backdrop's alpha, so with nothing under the glass (an
export of the pane alone) the line on the bevel vanished, where the old
glow raised the alpha and showed. Now the alpha rises as far as the lit
colour needs (`lit`), and stays the backdrop's wherever the light fits
under it, so renders over an opaque backdrop don't change.

Past `depth` + the bevel the rim light, the gradient and the bend are all
0, so those pixels take one sample of the backdrop and skip the light's
direction, facing and splay work, as the old glow's `reach` early-out did.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* M8: a kept glass shape works out only its bend again when the depth changes, and a core gets a wider margin (#1885)

Review follow-up. The field cache was keyed on the core's exact depth, so
every step of the Depth slider missed it and worked the whole shape out
again over a window twice as wide: coverage, distances, normals, the
feature transform and the blur, every frame, for every shape that isn't a
plain rounded rectangle. Only the bend directions depend on the depth. The
kept fields (`EdgeFields`: coverage, distances, normals) are now keyed
without it, and hold the bend directions for the last two depths asked
for beside them, so a new depth works out only those (`EdgeFields::bends`).
Two glass layers of one shape at different depths each keep theirs.

The margin a core takes was `reach` + 2 px past the plain one, but the
nearest core pixel can be √2 × `reach` away round a sharp corner, past
what that covers once `reach` is over about 91 px. It is now
1.5 × `reach` + 2 px past the plain margin. The cut-through-the-pane test
gets a 60-unit-deep look (a core 122 px in at 2×).

857d7089be M3: glass's light is a line on its bevel, and splay turns the bend towards the centre (#1888)
* M3: glass bends with the reference tool's thick-lens profile and splits its colours over 8 steps (#1885)

The backdrop bends most a 1-unit bevel in from the edge, falls off as the
3.5th power of the way out of the curve to nothing `depth` further in, and
moves a fifth as much on the bevel itself (it fell off as the square of the
way in from the very edge). Dispersion samples each channel at 8 steps along
the bend with a triangular window, red moving furthest and blue least (it was
three samples, blue furthest), as far apart as the reference tool's: at 100%
red and blue move 0.16 of the bend apart (`Glass::DISPERSION_SPREAD`).
`Glass::max_bend` bounds red's furthest step, so the backdrop read around a
pane covers every sample, and the field margin covers the bevel.

* M3: glass's bend stays within `max_bend`, checked on a single bright pixel too (#1885)

Review follow-up: the bend reaches `depth` × `refraction` a bevel in from
the edge, so `Glass::max_bend` drops its 0.999 and bounds it, as a test now
checks for several refractions. A single white pixel on black pins the
dispersion's triangular window, which a ramp and a flat backdrop can't tell
from one centred sample. The parity assessment records the bend, the
dispersion and how they were measured against the reference tool.

* M3: glass's light is a line on its bevel, and splay turns the bend towards the centre (#1885)

The light is a line on the 1-unit bevel added to the backdrop, as the
reference tool's: fully where the edge faces the light, none below 0.35 of
facing it and 0.6 as much on the opposite side, with a faint gradient across
the curve, 5% darker facing the light and lighter opposite. It was a glow
mixed towards white, as deep as `splay` made it, so `light_reach` goes.

`splay` turns the bend from along the edge's normal towards the way away
from the layer's centre, and no longer widens the light: files with a splay
above 0 look different. The direction to the centre is worked out in the
shape's own frame (`own_frame`, shared with the field cache), so cut renders
match the whole one byte for byte.

* M3: cut renders of glass match with splay turning a dispersed bend (#1885)

Review follow-up: the cut-versus-whole test had splay only on looks without
refraction, so no turned bend reached the dispersion. A look with splay 1 and
the default bend and dispersion now renders the same however it is cut. The
parity assessment records the light on the bevel and splay's new meaning.

* M3: glass's flat inside skips the bend's curve, and full dispersion stays within `max_bend` (#1885)

Review follow-up: `bend_at` returns 0 straight away past `depth` + the
bevel, where the curve and the bevel's easing are both 0, instead of
working out a power of 0 for every pixel of a pane's flat inside. A test
moves one white pixel along a row under every bend of the profile at full
dispersion and checks that no channel ever reads it further out than
`Glass::max_bend`, which sizes the backdrop read around a pane.

* M3: glass's light shows over a transparent backdrop, and its flat inside skips the light (#1885)

Review follow-up: the light was added to the backdrop's colour and then
clamped to the backdrop's alpha, so with nothing under the glass (an
export of the pane alone) the line on the bevel vanished, where the old
glow raised the alpha and showed. Now the alpha rises as far as the lit
colour needs (`lit`), and stays the backdrop's wherever the light fits
under it, so renders over an opaque backdrop don't change.

Past `depth` + the bevel the rim light, the gradient and the bend are all
0, so those pixels take one sample of the backdrop and skip the light's
direction, facing and splay work, as the old glow's `reach` early-out did.
