Subject: [PATCH] Share the video, with a link that ends in .mp4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The file URL ends in /public with no filename, which is fine for anything that
reads headers — it already serves Content-Type video/mp4 and a
Content-Disposition of final.mp4 — but clients that sniff the extension out of
the URL string get it wrong. A filename query is accepted and ignored by the
file service, so the link can end in .mp4 at a cost of a dozen characters.

The button uses the native share sheet where there is one, which on a phone is
the shortest path into a text message, and falls back to copying.
