* What the Android side of KML import still owns: recognising a KMZ and pulling the KML out of it.

*

* The converter itself is common code and tested in `feature/map`. These stay here because a zip archive and the JVM

* default locale are both platform concerns — the locale case in particular guards the formatting that once emitted

* `0,498` into the JSON and made every import silently draw nothing.
