+# clang-tidy configuration for WoWee
+# Targets C++20. Checks are tuned for a Vulkan/game-engine codebase:
+#   - reinterpret_cast, pointer arithmetic, and magic numbers are frequent
+#     in low-level graphics/network code, so the most aggressive
+#     cppcoreguidelines and readability-magic-numbers checks are disabled.
