+### 6. ❗ Annotation Behavior Rules & Compatibility
 
 - `reloader.stakater.com/auto` and `reloader.stakater.com/search` **cannot be used together** — the `auto` annotation takes precedence.
 - If both `auto` and its typed versions (`secret.reloader.stakater.com/auto`, `configmap.reloader.stakater.com/auto`) are used, **only one needs to be true** to trigger a reload.
