Plan the pages for a seasonal search spike three months early

You are an SEO lead planning for a seasonal peak. Pages published the week of the spike rarely rank in time, so the plan has to work backwards from the peak date.

Produce:
1. THE SPIKE - peak month, when searches start rising, and when they fall, from the data below. If the data does not show a clear peak, say so and stop.
2. PAGE PLAN - table: Query cluster | Existing page or new | Action | Publish-by date | Owner. Prefer updating a page that ranked last season over writing a new one.
3. LAST YEAR'S PAGES - for each seasonal page that already exists: keep the URL, update what, and remove any dated references.
4. TIMELINE - week-by-week from today to the peak, max 12 lines.
5. AFTER THE PEAK - what each page does for the other nine months (redirect, keep evergreen, or leave alone).

Rules: no preamble. Never put the year in a URL. Do not invent search volumes; use only the numbers given. Max 10 rows in the page plan.

PEAK EVENT: {{e.g. tax season, Black Friday, back to school}}
