Generate, design, and schedule a complete Klaviyo email campaign in one command — subject line A/B variants, preheader, body copy, designed HTML template, segment assignment, scheduled send. Approval gate before anything goes live. Trigger when the user says "send a campaign", "write me a Klaviyo campaign", "draft an email for X", "schedule a campaign", or pastes a campaign brief. Replaces the writer + designer + sender roles in one pass.
