A Dockerfile that builds the bundle and serves it from nginx, matching the
three games already on the site, and the metadata a page needs when it is
somewhere rather than on a laptop: canonical, Open Graph, the two JSON-LD
blocks, and a noscript that describes the game rather than showing an empty
div to anybody who does not run scripts.
No dev proxy, unlike its siblings. They post scores to a shared service and
this one has nothing to post: a game of Diplomacy is not a number, and a
leaderboard reading "reached eleven centres" would be a worse thing to know
about somebody than nothing at all.
The favicon is seven powers round a board in the seven colours the map uses,
with the one supply centre in the middle they are all looking at -- drawn
here rather than drafted in a tool, like every other mark in this
repository.
And a way back out, absolute rather than "/": this is served from a
subdirectory in production and from the root in development, so the relative
answer is right in one of those and points at the game itself in the other.
