# TOML - taplo
# Only the formatter is enabled. taplo-lint is intentionally omitted: it fetches
# the remote SchemaStore catalog on every run, which requires network access
# (breaking sandboxed CI) and is broken in the pinned taplo CLI ("data did not
# match any variant of untagged enum SchemaCatalog"). TOML syntax is already
# validated by the check-toml hook above, and taplo upstream is dormant.

# Pre-push safety net. The pre-commit cargo-fmt hook above reformats in place,

# fails). This hook re-checks at push time, mirroring CI byte-for-byte, so an
# unformatted commit is blocked locally before it can reach the runner. It runs
# only when the push range touches a .rs file, so Rust-free pushes pay nothing.
