+Associative container mapping `String` keys to `String` values.
+
+`StringMap` is an alias for `std::map<String, String>`.
+
+## Common Uses
+
+`StringMap` commonly appears in:
+
+- `context.params`
+- `context.get`
+- `context.post`
+- `context.cookies`
+- `context.session`
+- `context.header`
+
+Because it uses `std::map`, `map["key"]` will create an empty entry when that key does not already exist.
+
+Helpers such as `parse_query()` and `encode_query()` convert between query strings and `StringMap` values.
+
+## Related Concepts
+
+- PHP: associative arrays keyed by string, especially request bags like `$_GET` and `$_SERVER`
+- JavaScript / Node.js: plain objects, dictionaries, `Map`, and header or query objects in web frameworks
