+The default calendar mode is `systems`, while `any` preserves the older one-neutral-dot behaviour. Template file fields in both Periodic Notes and Date systems use a native `datalist` populated from every Markdown path in the vault (without the optional `.md` extension), so templates stored outside a conventional `Templates/` folder remain discoverable.

 ### Templater folder triggers
 
 Waypoint deliberately does not evaluate Templater syntax. For an interactive Templater template, configure Templater's **Trigger Templater on new file creation** mode for the relevant folder, then leave that date system's `templateFile` blank in Waypoint. Waypoint creates a safe fallback note from `typeProperty` and the selected `YYYY-MM-DD` date; Templater's folder trigger owns the rendered content, prompts, scripts, and cursor placement.
