  # push only on main; PR branches are covered by pull_request. Scoping push this

# libtile57 is the sole engine: the build is CGO and statically links the native
# lib from the public beetlebugorg/tile57 repo, built with Zig 0.16. That repo is
# the ./tile57 git submodule (go.mod's replace points at ./tile57/bindings/go, and
# the binding's cgo LDFLAGS at its zig-out/lib); its own submodules fetch the IHO
# S-101 catalogues. `submodules: recursive` checks it out at the committed pin, then
# we float it to the engine's latest main (the pin is just last-known-good).
# NOTE: correct-by-construction but unvalidated until pushed to GitHub.
