+// Launch page preference.

+// The app used to inject its manifest at runtime with
+// `start_url: window.location.href`, so installing from /metrictrack made the
+// installed app always open there. That mattered: not everyone wants the notes
+// page as their home.
+//
+// A static manifest can't carry a per-install start_url, and we need a static
+// same-origin manifest for share_target to register at all (a data: URI
+// manifest has an opaque origin, so scope resolution fails). So the preference
+// moves in-app: the manifest's start_url is "/", and we redirect from there.
+//
+// This is also strictly better than the old behaviour -- the old one froze the
+// home page at install time and could only be changed by reinstalling. This one
+// is editable in Settings.
