Deep Work Session Designer

I have {{X hours}} for deep work on {{PROJECT}} today.
Design a session plan with:

• Pre-work setup (5 min checklist)
• Main focus blocks (each with a concrete output/outcome)
• Strategic break timing (durations and activities)
• Stuck-point protocol (what to do if blocked)
• Shutdown ritual (wrap + next-step capture)
  Format as: Block | Duration | Objective | Steps | Break | Exit criteria.
  Optimize for cognitive endurance.
