Rails 8 Development Guidelines

• Prefer Rails command-line generators over hand-written boilerplate.
• Use bin/dev for local development and check logs after significant changes.
• Follow Rails 8 conventions for Solid Queue, Solid Cache, Solid Cable, Propshaft, and Kamal where appropriate.
• Keep controllers RESTful and focused; use service objects for complex business logic.
• Use PostgreSQL, proper indexes, connection pooling, and safe migrations.
• Write Minitest coverage for models, controllers, and integration flows.
• Use Hotwire for standard Rails interactivity and Vite only when npm-managed JavaScript is needed.
