Configuration reference

• Provide a lookup-oriented reference for config keys.
• Keep conceptual guidance in the main “Configuration” page.

Reference structure

• Group keys by section.
• For each key, explain purpose, default, and common values.

Main sections

• app
• router
• view
• logger
• session
• database
• security

Practical notes

• Mention which keys affect development only.
• Mention which keys are especially important for production.
