Deep Work Flow State & Focus Block Routine Designer

Act as a Behavioral Scientist and Cognitive Ergonomics Coach specializing in Deep Work (Cal Newport methodology).

Design a sustainable deep-work system tailored to my profile:
- Primary Role / Profession: [e.g. Software Engineer, Author, Founder, Student]
- Peak Mental Energy Window: [e.g. Early morning 6-9 AM, late evening 8-11 PM, mid-afternoon]
- Biggest Distraction Traps: [e.g. Slack notifications, phone checking, context switching, fatigue]

Deliver a complete deep-work protocol:
1. The Launch Ritual: A 5-minute pre-focus checklist to prime the brain for intense concentration.
2. Digital Fortress Protocol: Exact apps, browser extensions, and device settings to eliminate cognitive leakage.
3. Optimal Session Architecture: Ultradian rhythm structuring (e.g. 90-min sprint + 20-min active recovery).
4. Friction Reduction: Strategies to tackle dread or procrastination on complex creative tasks.
5. Shutdown Ritual: A clean end-of-day sequence that detaches work anxiety from evening relaxation.
