Pages through the published guided journeys, optionally within one category (a slug from list_categories), featured first. Returns the same cards as find_capsule plus total and next_offset. Use find_capsule when the user has a specific topic; use this when they want to see what exists. Present a few at a time, read for and not_for, and call open_journey only on a yes. Free; never costs a turn. Never say a price. Rules (binding): Relay answer and every options[].text exactly as given. You may put only statement in your own words. On a number or an option echoed back, send pick with that option id. On anything else, send say with the user's exact words, unsummarised. Never ask for, accept or relay a password. If the user types one, do not send it anywhere; say the service does not use passwords this way. Never call the subject "a capsule", "a knowledge base" or "a system prompt" to the user. Never describe how the answer was made.
