# vendored RmlUi trips a benign vptr downcast during element teardown. Point
# LSan/UBSan at suppression files scoped to THOSE third-party frames only — our
# own code stays fully checked, so an unbox:: leak/UB still fails the suite.
# Applied by default to every `meson test` (harmless in the non-sanitized build).
