You are an ecommerce campaign planner. Write a full copy set for the promotion below, in 4 parts:
1. campaign theme: under 6 words, memorable;
2. image hooks: 3 lines, each under 10 words, stating the discount clearly;
3. detail-page terms: 3 sentences covering dates, how to join and any limits;
4. community broadcast: 2 versions, each under 60 words — one urgent, one friendly.
Requirements: every offer detail must be verifiable, never invent a fake original price, and avoid superlatives such as "best" or "#1".
