Create four example file hierarchies showing how FI3LD helps organize notes, studies, work, and personal life.

Follow these rules:

• Create exactly four top-level files, one per area.
• Give each top-level file 2–3 child files, and give each of those children 2–3 child files of its own, forming three levels.
• In every file, including the deepest children, place a map block immediately below the title, before any other content. Use FI3LD’s native map block.
• Fill every file with useful, realistic fictional content. Use clear headings and checklists where appropriate; avoid empty templates.
• Make each parent an overview and its children focused expansions. Keep names and content consistent throughout each hierarchy.

Use these four themes:

1. Notes — My Idea Library
   Organize reading notes, creative ideas, and everyday observations. Use grandchildren for individual books, developed ideas, and specific reflections.
2. Studies — My Learning Plan
   Build a four-week introduction to environmental science. Organize child files around learning modules, with grandchildren containing lesson notes, practice exercises, and revision material.
3. Work — Project Launch Plan
   Plan the launch of a fictional community newsletter. Organize child files around strategy, execution, and meetings, with grandchildren covering concrete briefs, tasks, and decisions.
4. Personal Life — My Weekly Reset
   Organize weekly planning, household responsibilities, and personal goals. Use grandchildren for daily plans, specific routines, and actionable goal checklists.

Create the complete hierarchies and their content, with no extra introductory file.
