…e safety and prevent unnecessary warnings
…-canvas Upstream shesha-io#5383 (form designer layout refactoring) rewrote the mechanism this branch is built on: the canvas and its zoom moved out of the shared SidebarContainer into ZoomableCanvas/DesignerCanvas, and auto zoom now takes a measured containerWidth instead of deriving one from panel sizes, viewType and the config tree panel width. Both sides had independently switched to measuring the container, so this adopts upstream's version wholesale and re-applies only the percentage canvas width feature on top of it: - providers/canvas: upstream's removal of configTreePanelSize, viewType, DEFAULT_OPTIONS.sizes/gutter/modalMargins and the panel-size arithmetic in calculateAutoZoom; kept autoWidth, widthPercent, setAvailableCanvasWidth, parseCanvasWidthPercent, getCanvasLayoutWidth, clampZoom and constants.ts, which now also re-exports DEFAULT_OPTIONS through utils for ZoomableCanvas. - ZoomableCanvas now owns the measurement via useElementSizeTracking, gates auto zoom on !autoWidth and lays the canvas out at availableWidth / zoom. - Canvas CSS moved from sidebarContainer/styles to designerMainArea/styles; sidebarContainer is back to upstream's version untouched. - Dropped the local WorkArea wrapper - upstream applies sha-cs-work-area inside WorkArea itself.

The canvas carried a 24px bottom margin and a min-height budgeted around it (calc(100% - 24px)), so it ended short of its pane: a band of wrapper showing under its shadowed bottom edge. Dropping the margin and taking min-height to a full 100% closes the band. Both changes are needed together - a full 100% with the margin still in place overflows the pane by exactly that margin, which is a vertical scrollbar that is always present regardless of form length. Verified in the designer: canvas 1157x738 in a 1157x738 pane, no gap below, no scrollbars; still fills the pane for a short form and still grows past it and scrolls on the wrapper for a long one.
activeDevice decides which settings block every component renders with (getDeviceModel in dynamicComponent, effectiveDevice in formComponentModelPreparer), and in Canvas mode the reducer resolves it from the measured pane width. Switching to Canvas off a device preset cannot resolve the device at the point of the switch: designerWidth is still the width that preset pinned, so resolving from it just returns the pinned device. Only the measurement knows the pane. Publishing it from a plain effect meant it landed after paint, so a full-width canvas rendered one frame in the pinned device's settings - leaving iPhone SE showed a ~1900px canvas in mobile styling. Publish from a layout effect instead, and seed the measurement from the wrapper's clientWidth before the first paint, since useElementSizeTracking observes in a plain effect and its first callback also lands after paint. The reducer's own resolve on the mode switch is kept - it corrects the case where auto width is toggled off and on and designerWidth is still a measured value - but its comment overclaimed and its stated justification was stale; setAvailableCanvasWidth already re-resolves the device when the width itself has not moved. The test for this asserted the corrected device straight after the switch by pre-setting designerWidth to a wide value, which real usage never does, so it could not have caught this. It now drives the actual order: pin mobile, switch to Canvas, then measure - asserting the stale intermediate step explicitly, because that is the frame this fix keeps off the screen.
Multi-paragraph comments narrating why a single CSS property or hook exists. This repo merges from upstream, so every extra line is a future merge conflict, and they go stale faster than the code - one of them justified reducer behaviour that no longer existed. Comment-only: no code line changed.

Review caught that bounding vw in boundWidth was ineffective on the CSS-string path: CSS resolves 100vw against the browser viewport, so on a canvas narrower than the viewport the bounded value still overflows and is clipped. The comment and test asserting otherwise were wrong. vw is only container-relative once getWidthDimension rewrites it as a fraction of the canvas, so the bound moves to boundWidthToCanvas, which runs only where the canvas width is known. dimensionsStyles now leaves vw as entered. That also avoids overriding a deliberate 200vw on a rendered page, where dimensionsStyles is the styles path for ~60 components and there is no canvas to justify a clamp. Percentages are unaffected - CSS resolves those against the containing block on both paths, so they are bounded on both.

Device resolution
"Canvas" is a sizing mode, not a device, but styling only supports desktop/tablet/mobile — so the canvas must always resolve to one of the three.
resolveDeviceForWidthis called from the auto-width, percentage and measured-width paths.designerDeviceandwidthPercentare persisted and seeded, so a form opens with the styles last in effect instead of a hardcoded'desktop'.setAvailableCanvasWidthActionno longer returns early on an unchanged width — that guard was also skipping the device resolution, which could strand the device on'desktop'for a whole session. It still returns the same state object when nothing changed, so no extra re-renders.setCanvasWidthPercentActionresolves the device itself rather than depending on a measurement that may be a no-op.designerWidthis still the width that preset pinned, so only the measurement knows the pane. Publishing after paint showed one frame of a full-width canvas still rendering the pinned device's settings: leaving iPhone SE gave a ~1900px canvas in mobile styling.activeDevicefeedsgetDeviceModelindynamicComponentandeffectiveDeviceinformComponentModelPreparer, so that frame is every component's settings block, not just a width.applyCanvasSize— a second copy of the same device assignment, with no callers.Widths
wasClampedso the toolbar can warn.getCanvasLayoutWidth, so no route — toolbar, context API, persisted state — can exceed the pane.Heights
vhresolves against the browser viewport, which is taller than the canvas, so a component set to100vhalways overshot the device screen.allowForCanvasChromeHeightsubtracts a flat 20vh from an exact100vh; other values and units are untouched.Applied in two places, because the Container component emits its height through

Fixed heights stopped the canvas box from growing, so content taller than the canvas was clipped instead of becoming scrollable. Released to
min-height.overflow: clipon the canvas, so nothing is painted outside the device screen and the wrapper stays the single scroll container.min-height: 100%, no bottom margin. An earlier revision of this branch kept a 24px bottom margin and budgetedmin-heightaround it (calc(100% - 24px)), which left the canvas ending short of the pane: a visible band of wrapper under its shadowed bottom edge.

This branch now merges
upstream/main, which includes #5383 (form designer layout refactoring). That change moved the canvas and its zoom out of the sharedSidebarContainerintodesignerMainArea/ZoomableCanvas, and replaced the panel-size arithmetic incalculateAutoZoomwith a measuredcontainerWidth.Both sides had independently moved to measuring the container rather than deriving it from window and panel sizes, so this branch adopts upstream's structure and re-applies only the percentage-width feature on top of it:
