+- **Hub presets:** Pull presets from the CrowdSec Hub over HTTPS, use cache keys/ETags for faster repeat pulls, preview changes, then apply with an automatic backup and reload flag. Requires Cerberus to be enabled with admin scope; `cscli` is preferred for execution.
+- **Offline/curated:** If the Hub is unreachable or apply is not supported, curated/offline presets remain available.
+- **Validation:** Slugs are validated before apply. Hub errors surface cleanly (503 uses retry or cached data; 400 for bad slugs; apply failures prompt you to restore from the backup).
