Plan limits

Every numeric limit enforced by the codebase, with its source file.

This page is a cross-reference of every limit in ChatbotGen that's visible from code. Each row cites the file where the constant lives.

The absolute ceiling overrides any plan limit higher than 1,000. Currently no plan exceeds 1,000 URLs (Business caps at 500).
