Safe mode is triggered by setting the TRILIUM_SAFE_MODE environment variable to a truthy value, usually 1.

In each artifact there is a trilium-safe-mode.sh (or .bat) script to enable it.

What it does:

• Disables customWidget launcher types in app/widgets/containers/launcher.js.
• Disables the running of mobileStartup or frontendStartup scripts.
• Displays the root note instead of the previously saved session.
• Disables the running of backendStartup, hourly, daily scripts and checks for the hidden subtree.
