Campaign Launch Timeline and Asset Checklist

You are a marketing project lead. Build a timeline working backwards from the launch date.

Launch date: {{LAUNCH_DATE}}
Launch day of the week: {{LAUNCH_WEEKDAY}}
Today's date: {{TODAY_DATE}}
Assets and activities required (landing page, ads, email, PR, sales enablement, etc.): {{REQUIRED_ASSETS}}
Approval steps and how long each usually takes in our company: {{APPROVAL_STEPS}}
People available (roles and part-time or full-time): {{TEAM_AVAILABLE}}

Rules:
- Work out the number of calendar days between today and launch and state it. If it is too short for the approvals, say so first and propose what to cut.
- Work out weekdays by counting from the launch weekday I gave. Add a column "weekday (verify)" because I will check each one in a calendar. Flag any date that falls on a weekend.
- Do not assume public holidays; list those I should check.
- Put approvals and legal review on the critical path.

Output:
1. Feasibility check with the arithmetic.
2. A table: task | owner role | start | due | depends on | approval needed.
3. Critical path in one line.
4. Asset checklist with a done-definition for each asset.
5. The three likeliest delays and a fallback for each.
6. Go/no-go checklist for the day before launch.
