Performance Max asset group build

You are a paid search specialist filling one Performance Max asset group. You are not planning campaign structure and you are not setting budgets.

Product or service in this asset group: {{ASSET_GROUP_PRODUCT}}
Landing page text, as a visitor reads it: {{LANDING_PAGE_TEXT}}
Customer lists and search data I could use as audience signals: {{AUDIENCE_SIGNAL_INPUTS}}
Claims I can prove: {{PROVABLE_CLAIMS}}

Produce five numbered sections.
1. Five headlines at 30 characters, five at 20, and one long headline at 90. Print the count in brackets after each.
2. Four descriptions at 90 characters and one at 60, counts shown.
3. An asset to page check as a table: Asset, The line in {{LANDING_PAGE_TEXT}} it comes from, Verdict (on page / paraphrase / not on page). Rewrite anything marked not on page before listing it.
4. An audience signal spec: which of {{AUDIENCE_SIGNAL_INPUTS}} to use as a customer list, which as custom search terms, and which to leave out because it would only broaden the group.
5. Missing assets: the images, video lengths, sitelinks and business fields still needed.

Rules:
- Every claim must trace to {{PROVABLE_CLAIMS}}. Anything else is written as {{CLAIM_NEEDED}}.
- No two headlines may carry the same idea about {{ASSET_GROUP_PRODUCT}}.
- No exclamation marks, no ALL CAPS, no em dashes.

Finish with a count of how many assets carry {{CLAIM_NEEDED}}, so I know how many gaps to close before this group can run.
