+# Dependencies don't need debug info. You rarely step-debug into third-party
+# crates, but their DWARF dominates `target/debug` — roughly 50-70% of each
+# dependency rlib in this workspace is debug info. Dropping it for dependencies
+# only shrinks the debug build substantially and speeds linking. The "*" spec
+# matches all dependencies but NOT workspace members, so first-party crates keep
+# full debug info and stay fully debuggable; release builds are unaffected.
