RoR Project Documentation (docs/)

Standard structure to include in each project:

docs/
├── index.md
├── 01_project_overview.md
├── 02_setup_instructions.md
├── 03_architecture.md
├── 04_domain_model.md
└── 05_prompt_canvas.md

Each file should explain not just what but why decisions were made, with step‑by‑step detail and inline code examples.
