Try it: pictures and boards

Type or say	The viewer should see	Watch out for
"Make a poster for a jazz night called Blue Hour."	A picture card. Because it has text, the Spark uses Detailed.	Detailed takes around 40 seconds. Fill the pause.
"Now make it red."	The same card updates, and earlier versions are kept.	None.
"Make yourself a new profile picture, more playful."	Three options on a card. Tap one to set it.	Each option is charged like a picture. Up to 12 suggestions a day.
"Sketch the user flow for signing up."	A board card that draws itself step by step.	None.
Open the board and switch to Edit, then move a box.	You can change the board yourself.	None.

Avoid in a demo: asking for transparent backgrounds or masked edits (not supported), and sharing a board link in public (links cannot be switched off yet).
