fix(configurator): size the shell by its container, not the viewport - #706
Merged

Conversation
The studio chrome decided its whole desktop-vs-mobile layout from the browser viewport via Tailwind `md:` (@media 768px). When the configurator is embedded in a container narrower than the viewport — the WP admin page beside the ~160px admin menu, or the plugin's ~420px frontend overlay on a desktop-width page — the viewport is still >=768px, so the full desktop three-column layout (208px labelled rail + 360px panel + preview) was forced into a box that could not hold it. Most visibly, SidebarNav rendered its 208px labelled rail inside the 420px overlay, squeezing the token panel to ~212px ('too narrow for its data'). Make the shell a CSS container (`@container`) and convert the layout-governing breakpoints in App.svelte and SidebarNav.svelte from viewport `md:` to the container variant `@3xl:` (48rem = 768px — the exact same threshold, now measured against the space we're actually given). Standalone is unchanged (container == viewport); embedded hosts now collapse to the compact rail / mobile layout when they're narrow. Unlabelled panels/inputs were already fluid, so no other files change. Note: unnamed container queries don't fall back to the viewport, so a host that mounts SidebarNav without an `@container` ancestor safely gets the compact 56px rail.

Greptile SummaryThe PR makes the configurator shell respond to its allocated container width instead of the browser viewport.
Confidence Score: 4/5The PR appears safe to merge, with a non-blocking focus-management edge case when an open drawer crosses the desktop container breakpoint. The primary container-responsive layout conversion is internally consistent, but CSS can hide a mounted drawer without running its focus-restoration cleanup.

When an open drawer's container grows past 768px, @3xl:hidden hides the dialog without clearing navDrawerOpen, so the focus action is not destroyed, focus is not restored to the trigger, and a hidden aria-modal dialog remains mounted.
…ktop width Addresses review feedback on the container-query conversion: with the drawer gated by `@3xl:hidden`, growing the shell past the 768px breakpoint only CSS-hid an open category drawer — the aria-modal dialog stayed mounted and use:drawerFocus never restored focus to the trigger. Observe the shell's own box (the @container element) with a ResizeObserver and clear navDrawerOpen once it reaches the desktop breakpoint, so the {#if} block unmounts, focus is restored, and no hidden modal lingers. Matches the CSS threshold exactly (DESKTOP_SHELL_PX = 768 = @3xl).

Addresses review feedback: the overlay seeds its active panel from the persisted `slashed-overlay/domain`, which can hold ids retired by the framework's domain regroup (Shadows/Effects -> Depth). Neither the vendored SidebarNav nor DomainPanel handle them any more, so a returning user would land on a dead, unreachable selection. Map legacy ids to their canonical successor before seeding `domain` (misc stays live as 'System', so it's untouched). Also re-vendors App.svelte with the upstream drawer-reconcile fix (codeslash-dev/SLASHED#706) and rebuilds the committed admin-app bundle.

- Around line 63-64: Update the desktop shell observer threshold near
DESKTOP_SHELL_PX to derive the breakpoint from the root HTML font size so it
remains aligned with the `@3xl` CSS breakpoint when the root font size is not
16px. Add a regression test covering a non-16px root font size and verifying the
observer uses the corresponding threshold.

…n close Two review follow-ups on the drawer-reconcile logic: - Derive the ResizeObserver threshold from the root font size (48rem, resolved against document.documentElement) instead of a hardcoded 768px, so it tracks the `@3xl` container breakpoint even when a host sets a non-16px root font size (rem — and Tailwind container breakpoints — resolve against the root). - When the breakpoint close hides the drawer, its original trigger is now `@3xl:hidden` (offsetParent === null); restoring focus there would drop it to <body>. drawerFocus now restores to the trigger only if it's still visible, otherwise moves focus to the visible desktop rail's current item.

Problem
After the recent configurator UX work (grouped nav IA, Depth/System panel merges, glance previews), the editor looked too narrow for its data when embedded — most obviously the WP plugin's ~420px frontend overlay, where the token panel was squeezed to about half its width.
Root cause
The studio chrome derived its entire desktop-vs-mobile layout from the browser viewport using Tailwind's
md:prefix (@media (min-width: 768px)). There are zero container queries in the chrome. When the app is mounted in a container narrower than the viewport — the WP admin page beside the ~160px admin menu, or the ~420px slide-in overlay on a desktop-width page — the viewport is still ≥768px, somd:fires and the full desktop three-column layout (208px labelled rail + 360px panel + preview) is forced into a box that can't hold it.The regression was introduced in
28973ea(grouped, named navigation IA):SidebarNavwent from a fixedw-14(56px icon rail) tow-14 md:w-52(56px / 208px labelled). In the 420px overlay on a desktop viewport that rail balloons to 208px, leaving theDomainPanelonly ~212px.Fix
Make the shell a CSS container (
@container) and convert the layout-governing breakpoints inApp.svelteandSidebarNav.sveltefrom the viewportmd:variant to the container variant@3xl:— which is 48rem = 768px, the exact same threshold, just measured against the width we're actually given instead of the viewport.@3xltriggers at the same 768px asmddid.Only the shell uses responsive prefixes; the panels/inputs were already fully fluid, so no other files change.
Notes
SidebarNavwithout an@containerancestor safely defaults to the compact 56px rail.StudioHeader/PreviewPanelkeep theirsm:/md:prefixes: they aren't used in the overlay and degrade gracefully (the header scrolls), so they're left out of this change to keep it focused.Verification
svelte-check: 0 errors / 0 warnings.vite build: succeeds; emitted CSS contains.@container{container-type:inline-size}and@container (width>=48rem){ … .@3xl:w-52 … }— the@3xl:classes compile to a real 768px container query.Downstream (WP plugin)
The plugin (
codeslash-dev/SLASHED-Plugins) vendors thisconfigurator/srctree. A companion PR there adds the@containeranchor to the frontend overlay and refreshes its stale domain labels; it needs this change synced (release + repin) to go fully green.Summary by CodeRabbit
