Usage
MfeRemoteDebugOverlay and MfeRemoteDebugCategory from @prepared911/ui/mfe-remote-debug-overlay. The shell portals it into document.body when ?debug=true is set; remotes never render it.rect in viewport coordinates. The ring follows the rect, and the category picks its color: registry (green), local (amber), trunk (light blue), pull request (violet) or unresolved (red).local, registry, trunk, pr or unresolved) in strong text, followed by the host's own label, the remote id, such as map.background-color over --duration-default on --easing-standard, and switches instantly under reduced motion. Only the label takes pointer events; the ring never blocks clicks on the content beneath it.--z-max, the top of the layer scale, so a drawer, popover, toast or tooltip never covers it. Content a native dialog opens with showModal() sits in the top layer, which no z-index outranks.
