Stores the choice in options(ggconsulting.locale = ...). The active
locale is read by the formatter helpers (fmt_number(),
fmt_currency(), fmt_month(), etc.) when their locale argument
is NULL. Defaults to "pt-BR"; "en-US" is always available.
Usage
ct_locale(locale = c("pt-BR", "en-US"))Value
The previous locale, invisibly. Use it to round-trip:
old <- ct_locale("en-US"); ...; ct_locale(old).
Details
Does not touch Sys.setlocale() — that's OS-dependent and breaks
on Windows CI. ggconsulting ships its own month tables and formatting
marks instead.
