create_card
Create a URL reference or an editable note in Material. Use a note for any synthesized or authored writing (it is editable by you and the user); use url for an external reference. When organizing a canvas by theme, create one note per theme as a cluster header and give it a placement above its cluster. Demo canvas — the change is visible live but ephemeral (resets on reload).
