Centralized property definition system for managing contact fields (HubSpot-style).

Two Approaches Available:

1. Centralized Definitions (Recommended for CRM)

• Define properties with types (text, number, date, select, boolean)
• Organize in groups (Contact Info, Company Info, Custom Fields)
• Set validation rules and default values
• Create dropdown options for select fields
• Manage through UI (create, edit, delete, reorder)

2. Schema-less (Flexible)

• Add any property on-the-fly to contacts
• No central definition needed
• Maximum flexibility for integrations
• System discovers what's in use

Both approaches can coexist!

Property Types:

• text, textarea, number, date, datetime
• boolean, select, multi_select
• url, email, phone, json
