補習班 LINE 群發三連發（考前倒數催報式）

prompt

Write 3 LINE official account broadcast messages for {school_name} promoting {course_name} as {exam_name} approaches, addressed to parents. Message 1 (14 days out): lead with a practical study-planning tip, course mention last — value before pitch. Message 2 (7 days out): social proof — seats filling fast, one short anonymous parent quote, and the remaining-seat count {seats_left}. Message 3 (3 days out): final-call urgency with the enrollment deadline and {enroll_incentive}. Keep each message under 250 characters, insert a line break every 1-2 sentences for mobile reading, use exactly one emoji per message, and end each with a tappable CTA line. Tone: a warm, trustworthy teacher — never a pushy salesman.
