Interface DiagramOptions

Quiet time after an edit before changed blocks re-render; 300ms by default so rendering never competes with typing. 0 renders synchronously on every transaction.

Prefix of the message shown when the renderer throws or rejects.

Code block languages that get a preview; ['mermaid'] by default. Matched case-insensitively.

Text shown while a block's first render is pending; 'Rendering diagram…' by default. Later re-renders keep the previous diagram in place (dimmed via the pending class) so the block does not jump between sizes.
