waitForElements() polled for .comfyui-menu, which the current frontend no
longer renders, so its promise never resolved. init() was stuck on that
await forever: the toolbar was never built and the Shift+WASD shortcuts
were never bound, while the requestAnimationFrame poll kept spinning for
the life of the session.
Docking into the DOM is no longer viable either way. The topbar is Vue
managed, so a card injected next to the Run button is wiped on the next
re-render, and the supported legacy slot (app.menu.element) lives inside
the Run button's own card, which would drag our toolbar around with it.
So the toolbar is now always a fixed element on document.body, like the
resource monitor, and docking is positional rather than structural: drop
it anywhere over the top bar row and it aligns to that row's centre,
keeping the x the user chose and stepping aside from the Run card. The
band geometry is read through data-testid hooks with a plain fallback, so
a future frontend redesign degrades to floating instead of vanishing.
