Produce JS-visible string results as UTF-16 at their source, including numeric formatting, BigInt and BigFraction formatting, URI encoding, console formatting, parser errors, regular expression errors, Intl and Temporal records, LibUnicode locale boundaries, and LibWeb bindings. Handle fractional radix formatting through the UTF-16 builder view.
