Auto-generated from the source PR above.

Reviewer checklist

Before merging, confirm each item below. The validator catches structural problems (raw HTML, dangerous URLs, secrets); these items need a human eye.

• Anchor text on every new link reads honestly — no click here, no link text that contradicts its target host.
• Every newly introduced external URL (listed below) points to a host you expect to see in Coinbase docs.
• Frontmatter title / description still match the page's role (reference vs. overview vs. conceptual).
• Any <Warning> added describes a real breaking change in the source PR, not a paraphrase the model invented.

Newly introduced external URLs

No new external URLs in this sync.
