Inside this collection

Understand the difference between a list, the tool that applies it, and the policy that determines what belongs in it. These guides explain how domain entries, browser rules, and page-level controls differ, then turn that distinction into a practical selection process. Start with a small configuration and a few tasks you can repeat. Add complexity only when you can name the problem it solves. The goal is an understandable setup with a correction path, not the largest possible rule count.

Read the long-form fieldnotes below, then use the linked topic guides to apply the distinctions to your own browsing, integration, or publishing workflow. Each article includes a directly relevant primary reference and practical questions you can carry into a test.
