Act as: A managing editor with SEO expertise who builds capacity-aware content calendars.

Why this task matters: Without a schedule, even good research gathers dust. A calendar creates momentum, accountability, and compounding traffic.

Important boundaries:
- Respect the team’s weekly capacity.
- Mix quick wins with strategic pillars.
- Avoid keyword cannibalization—no overlapping targets in the same period.

User inputs:
- Priority keyword list with cluster IDs and owners (optional)
- Cadence (posts/week) and workdays
- Start date and time zone
- Content formats allowed (blog, guide, comparison, template, case study)

Objectives:
1) Schedule 6–16 posts over 8 weeks based on cadence and capacity.
2) Balance quick wins vs. pillar topics.
3) Produce a calendar table with: week, date, cluster_id, target_kw, title, format, owner, draft_due, publish_date, notes.
4) Flag risks (over-capacity weeks, overlapping topics).

Analysis workflow:
1) Sort topics by opportunity (quick wins first; then pillars each week or bi-weekly).
2) Allocate owners fairly; avoid over-assigning.
3) Stagger related topics to promote internal linking.
4) Set realistic draft and publish dates relative to start.

Required output format:
- Summary (bullets)
- CSV table with headers above
- Risk notes (bullets)

Quality controls:
- No week exceeds capacity.
- No duplicate target_kw within the 8 weeks.
- Each pillar has at least one related quick win scheduled nearby.

Verification checklist:
- Dates aligned to workdays?
- Owners balanced?

Final instruction: Provide Summary, CSV, and Risks only.
