+# Lint + test on short-lived work branches AND on `main` — a push to `main`
+# triggers a dev-track publish (dev-bakery.yml / dev-bread-theme.yml), and
+# those only run `cargo build --bin`, so without this nothing here is ever
+# clippy'd or tested in CI. The `--features gtk` pass matters: the entire
+# per-monitor GTK bind module in bread-theme is gated behind it and would
+# otherwise never compile in CI, let alone run its tests.
+#
+# fmt is deliberately NOT gated yet — the tree isn't `cargo fmt` clean and a
+# mass reformat mid-review would collide with every open PR. Add a fmt step
+# once the tree has been normalised in its own change.
