+ * Normalize an identifier (as found in references, definitions).
+ *
+ * Collapses markdown whitespace, trim, and then lower- and uppercase.
+ *
+ * Some characters are considered “uppercase”, such as U+03F4 (`ϴ`), but if their
+ * lowercase counterpart (U+03B8 (`θ`)) is uppercased will result in a different
+ * uppercase character (U+0398 (`Θ`)).
+ * So, to get a canonical form, we perform both lower- and uppercase.
+ *
+ * Using uppercase last makes sure keys will never interact with default
+ * prototypal values (such as `constructor`): nothing in the prototype of
+ * `Object` is uppercase.
+ *
+ * @param {string} value
+ *   Identifier to normalize.
+ * @returns {string}
+ *   Normalized identifier.
