Generate an invitation design
lemonvite_generate_designUse this when the user wants Lemonvite's design engine to create the invitation artwork — because this assistant cannot produce images itself, or because the user asked for a Lemonvite design. Describe the look in design_brief (theme, colours, mood, motifs); the event date, time and venue are lettered onto the design automatically unless include_event_details is false. A reference_image from the conversation guides the engine's style. Each call spends one of the host's design generations (new accounts start with 5; every purchased publish credit adds 5) and REPLACES the current artwork (the previous design stays in the event's design history on the website), so confirm with the user before calling it. If this assistant already made an image in the conversation, attach it with invitation_image on lemonvite_update_invitation instead. Never call it merely because designs or themes are being discussed.
