TL;DR

Page-contributed sidebars were fixed-width while the conversation sidebar could be resized. This reuses the same host resize track and saved width so page sidebars stay adjustable across destinations.

Why

The page slot did not mount the resize control, leaving plugin-provided sidebars unable to match the conversation sidebar's width behavior.

What

• Wraps page-contributed sidebars and their unavailable fallback in the existing ResizableSidebar.
• Shares the per-community width across Messages and plugin pages, including the existing drag, keyboard, reset, and clamp behavior.

How

AppShell reuses the existing sidebar component; the page layout role fills its host-resized track. No second resize preference is added. A workspace switch cancels the old drag without remounting the sidebar content.

Browser coverage

The browser journey checks pointer dragging and the resulting host-track width, which jsdom cannot verify. The app test covers saved width across a Messages/page switch and the unavailable fallback. No browser cases were removed. The browser journey failed before the fix because the resize separator was absent, then passed in Chromium and WebKit. The Todos journey passed on both main and the earlier candidate. A component regression reproduced a drag crossing workspaces, then passed after cancellation preserved both saved widths and the mounted draft.

Risk

The app shell reuses existing persistence and resize bounds. The shared handle now restores drag previews during layout cleanup so an old gesture cannot overwrite another workspace's width.

Testing

No manual testing. The captures below show the fixture page sidebar before and after resizing.

Bigger picture

This builds on #1565, which added plugin-contributed sidebar sections. Related work remains separate: #1444 changes linked-chat sidebar placement, #1556 adds download feedback, and #1620 adds team review UI. This PR only makes page sidebars use the shared resize track.

Independent systems/lifecycle, correctness/security, and product/accessibility lanes completed; the PR description and both images were also inspected.
