 `:latest` wird nur durch Pushes auf `main` überschrieben. Feature-Branches bauen immer, lassen `:latest` aber unberührt.
+
+## Rebuild without code changes
+
+To trigger a rebuild (e.g. to pull latest `apt upgrade`):
+
+**Option 1 — empty commit:**
+```bash
+git commit --allow-empty -m "chore: rebuild to pull latest apt upgrades"
+git push
+```
+
+**Option 2 — manual trigger:** Use the "Run workflow" button in the Gitea Actions UI (`telegraf-snmp-unifi` workflow only).
