Break down a large, complex task into smaller, actionable sub-steps with effort estimates, dependencies, and an optimized execution order so I can make steady progress without getting stuck.

DECOMPOSITION INSTRUCTIONS:
1. Restate the task in one clear sentence to confirm understanding.
2. Identify the major phases or milestones (3-6 top-level groupings).
3. Within each phase, list concrete sub-steps that each represent a single work session or deliverable.
4. For every sub-step, provide:
   - A clear action verb title (e.g., "Draft outline," "Set up database schema")
   - Effort estimate: SMALL (under 1 hour), MEDIUM (1-4 hours), or LARGE (half-day or more)
   - Dependencies: which other steps must finish first (use step IDs like 1.1, 1.2)
   - Deliverable: what "done" looks like for that step
5. Flag any steps that can run in parallel.
6. Suggest an optimal execution order that respects dependencies and front-loads high-risk or blocking items.
7. Provide a summary table: total step count, estimated total effort, critical path length, and the first three steps to start immediately.

OUTPUT CONSTRAINTS:
- Use numbered hierarchy (1.0, 1.1, 1.2, 2.0, ...) for easy reference.
- Keep each step description to one sentence.
- Mark the critical path steps with "[CP]".
- End with a "Quick Start" section listing the first three actions I should take right now.
