Structural names —\n   function parameter names, object property keys — are never resolved.\n\nEach name resolves through the following tiers; the first match wins:\n\n1. The configurable type map provided to the toolchain, which associates\n   names with documentation URLs. An example type map is available for\n   viewing [here](https://github.com/nodejs/node/blob/main/doc/type-map.json).\n2.

Web platform APIs documented on MDN, matched case-insensitively.\n4. Dotted-name heuristic: names containing `.` are split on the first `.` to\n   derive a module name and member identifier, producing a cross-document\n   link of the form `<module>.md#<identifier>`.\n\nA name that no tier resolves stays plain — this is not an error.","summary":"Each annotation resolves to a set of hyperlinks:","examples":[],"children":[]},{"kind":"section","id":"84-rendering","name":"8.4.
