+              DashCaddy stores up to <strong>500 health check entries per service</strong> (plus container statistics and event logs).
+              At high check frequencies this may consume significant disk space — on a host with many services the history file can grow to tens of megabytes.
+              Adjust the <strong>health check interval</strong>, <strong>max entries per service</strong>, and <strong>health retention period</strong> in <strong>Disk Safety</strong> (the 💾 Disk button in the top bar) to control disk usage.

+            ⚠ <strong>Disk impact:</strong> Lowering the health check interval increases how often data is written to disk.
+            DashCaddy caps history at <strong>max entries per service</strong> and prunes entries older than the retention period,
+            so these two values together determine steady-state disk usage. For busy hosts, prefer a longer interval (60–120s)
+            and a lower entry cap.
