* fix(vue): release CanvasKit WebGL contexts when canvases go away
GetWebGLContext registers a canvas's context in CanvasKit's global
table, and the surface manager only called deleteContext on a failed
setup. Every destroyed canvas, and every surface rebuilt after a resize
or color-space change, stayed registered, and through the canvas
element CanvasKit kept the closed editor's component tree, store, and
graph alive.
The manager now keeps the handle and releases it on rebuild and
destroy. deleteContext also leaves CanvasKit holding the last current
context, so when the released context was current, a parking context
on a 1x1 offscreen canvas becomes current instead.
* fix(core): uninstall an editor's text measurer when it closes
setCanvasKit installed a global text measurer that closed over the
editor and its renderer, and nothing uninstalled it, so the last editor
to set up a canvas stayed alive after its tab closed and layout kept
measuring with its destroyed renderer. installTextMeasurer returns an
uninstall function; an editor uninstalls its measurer when disposed or
when its last renderer goes, and the most recent measurer still
installed takes over.
* fix(app): give editor stores their own effect scope
The first store is created during WorkspaceView's setup, so effects
created while building it joined the view's scope. Their cleanups
stayed registered there after the store was disposed and kept the
startup document alive for the life of the app. Stores now build inside
a detached effect scope that dispose stops.
* fix(app): follow the active tab in app-level editor subscriptions
App.vue provided a proxy that resolved to whichever store was active
when a property was read, so app-level composables such as the menu
and keyboard commands subscribed once to the startup store. They missed
events from later documents and kept that store alive, and Undo and
Redo availability came from the first document's history.
The app-level editor now moves event subscriptions to the active store,
and each tab's editor UI gets its own store through EditorTabScope, so
per-tab components stay bound to their document when it closes.
Selection capabilities read the undo history lazily instead of
capturing the first store's manager.
* fix(app): stop keeping closed documents in chat history and startup
The chat history kept the last editor it served only to compare it with
the next one; it now holds it weakly. WorkspaceView's first tab was a
top-level setup binding, which Vue keeps on the instance; it is now
block-scoped.
* test(app): check that documents closed in tabs are released
Opens a document in a new tab three times, closes each with discard,
forces garbage collection, and checks that weak references to the
closed graphs clear. On master all three graphs stay alive.
* refactor(app): provide the tab's store from a tab-keyed editor view
EditorTabScope existed only to provide a tab's store to its editor UI.
WorkspaceView now keys EditorWorkspace by tab, whose contents were
already remounted per tab, so the view provides the tab's store in its
own setup and the wrapper component goes away.
* fix(app): stop a store's effect scope when building the store throws
Effects created before the throw would otherwise stay alive with the partial store, which no caller can dispose.
* test(app): avoid empty callbacks in the store scope tests
* fix(core): let fill text share an auto-layout row
Fill frames grow and shrink from a zero flex basis, so fill siblings split a row's free space. Fill text only got flexGrow, and its measure function capped it at its stored width, 100px for new text, so seven fill labels in a 280px row each kept 100px and overflowed. Without a measurer, the fallback pinned that width and set no grow at all. Fill text now uses the same zero basis as fill frames on both paths.
* fix(design-jsx): read repeat() and minmax() in grid tracks
Track lists were split on whitespace, so columns="repeat(7, 1fr)" became the tracks repeat(7, and 1fr), read as fixed 0px and 1px columns that collapsed the grid. Tokens inside parentheses now stay together, repeat() expands its tracks, minmax() grows like its maximum, and a track the grid cannot express sizes to its content instead of to 0.
* refactor(scene-graph): parse CSS grid tracks with postcss-value-parser
design-jsx read repeat() and minmax() with a hand-written tokenizer and regexes, while dom-css already parses CSS values with postcss-value-parser. Track lists are now parsed in @open-pencil/scene-graph/css on that library, where both packages can use it, and design-jsx calls it. dom-css's hand-written declaration of the library's types is replaced by the types the library ships, which the shared module needs. The Scene Graph guide records that CSS values are parsed there.
Three defects a confidential Figma file surfaced, each reproduced by a
test that fails without the change.
A page's background lived only in viewport state, so an imported canvas
colour never reached the canvas and an edit was lost on the next page
switch or save. It is read from and written to the page's paints, which
the Figma API and export already carry.
Fixed-size text in a Hug container reported no intrinsic cross-axis
size, so a stretched label collapsed and clipped beside smaller
siblings. Yoga now measures it.
Populating a page resynchronised an instance whose text the file had
already resolved, replacing it with the component's default.
