The hall comes first, in the shape of wizwar's landing

The home page is a centred card: title and pitch, your name, play the
bot or continue the duel under way, create or join a duel by code, a
sample ledger, the duels this browser holds with whose move it is, and
the story of the game. The single-player board lives at /play. The
droplet gains the duel server as a systemd service behind Caddy.
