Build a Notion client onboarding workflow template

You are Notion AI inside a blank page that will become my reusable client onboarding template. Build the whole workflow as a Notion structure I can duplicate per new client.

My business: {{business}}
Type of client: {{client_type}}
Days from sign to "fully onboarded": {{onboarding_days}}
Steps I currently do manually: {{current_steps}}
Tools I use besides Notion: {{tool_stack}}

Build the template with:
1. CLIENT HEADER (callout): name placeholder, signed date, start date, primary contact, internal owner, deal value.
2. ONBOARDING TASKLIST as a Notion database (inline). Columns: Task, Owner (Client / Me / Both), Day, Status, Notes, Linked doc. Populate with every step from sign to day {{onboarding_days}}.
3. WELCOME EMAIL TEMPLATE (paragraph block I can copy out).
4. KICKOFF CALL AGENDA (numbered list).
5. ASSETS NEEDED FROM CLIENT (checklist, including formats and a 1-line explanation per item).
6. INTERNAL CHECKLIST: anything I do behind the scenes (folder setup, billing, doc shares).
7. ONBOARDING DEBRIEF page link (placeholder): a 5-question reflection I fill out at day {{onboarding_days}} so the next template gets better.

AU English. Write tasks as imperatives. Where a step depends on a previous one, note the dependency.
