Description: staunton — chess publishing for Typst: boards, FEN/PGN diagrams,
tables, outlines. This is a breaking 2.0.0 release that redesigns the game /
PGN surface around two rules: there is one way to do each thing, and a move is
something you pass rather than something smuggled inside a value.
parse-pgn / parse-fen become games / game / position;
diagram-after(g, "17w") becomes diagram(g, at: "17w"); positions no longer
carry a hidden move payload, so move-quality badges and %cal / %csl
annotations require the game plus at:. Nearly every function is now
f(subject, setting: ..) — one positional argument, the rest named. Also new:
arrow tip and fade styling (the barbed "hook" tip is the new default), a
last-move marking, and figurine notation (♘f3) accepted as input alongside
localized SAN. No aliases were kept for the renames. Full changelog at:
https://github.com/ndg6/staunton/blob/v2.0.0/README.md#200

Note: 1.1.0 was a GitHub-only release and was never submitted here, so this
updates Universe from 1.0.0 straight to 2.0.0.
