Download maps, routing packs, guides, ZIM archives, model files, and RSS/weather caches while you still have bandwidth.
Maps, knowledge, private notes, local source search, and field tools for phones that still need to work after the network is gone.

Use the release checklist before presenting Ark as production-ready.
