locale is a BCP-47 tag (e.g. 'de-DE'); when omitted the formatters use
the locale-agnostic utils defaults (formatPrice etc.) so the chart stays
byte-for-byte identical to the pre-C6 behavior — opting into i18n is
explicit. overrides patches any subset of Messages; unspecified
keys fall back to DEFAULT_MESSAGES.
The returned date memoizes one Intl.DateTimeFormat per distinct
resolution bucket so axis rendering doesn't reallocate per label.
