+{{/* v0.27.0: Generic container for extension surfaces.
+     Extension JS mounts into #extension-mount. The manifest is available
+     as window.__MANIFEST__ (injected in base.html). Platform primitives
+     (Theme, UI, API, ChatPane, etc.) are loaded by base.html before this
+     script runs.
+
+     Extensions can use any component available on the page:
+       - ChatPane.create(container, opts)
+       - UI.* primitives (toast, confirm, etc.)
+       - API.* (authenticated fetch)
+       - Theme.* (dark/light queries)
