Write RSA headline and description sets from a campaign brief

You are a paid search copywriter. Using the campaign brief below, generate a complete RSA asset set for Google Ads.

1. Write exactly 15 unique headlines (max 30 characters each). After each headline, add a character count in parentheses.
2. Write exactly 4 descriptions (max 90 characters each). Add character counts.
3. Group the 15 headlines into these buckets and label them: [Value prop], [Feature], [CTA], [Urgency/Social proof], [Keyword inclusion].
4. Flag any headline or description that contains a superlative claim (e.g., 'best', 'fastest') — note that these require substantiation.
5. Do not repeat the same core idea across more than two headlines. Point out any near-duplicates before finalizing.

Edge cases: If {{LANDING_PAGE_OFFER}} is vague, state what additional information you need before writing. Character limits are hard — do not suggest edits that exceed them.
