# i18n.sh — UI language + regional locale for taler-monitoring console + HTML
#
# UI language (mon badges / sticky chrome):
#   TALER_MON_LANG=en|fr|de
#   TALER_MON_LANG_SET=1  → explicit (--lang); do not override.
#   Auto (SET≠1): TALER_DOMAIN_LANG from domains.conf `lang` column.
#   de is supported but never a stock profile default (no domains.conf row uses lang=de).
#
# Regional locale (l10n defaults, BCP 47 — not the same as UI lang):
#   TALER_MON_LOCALE / TALER_DOMAIN_LOCALE e.g. fr-CH, de-CH
#   From domains.conf `locale` column (fr-CH for FP, de-CH for others).
#   Aliases ch-FR / ch-DE accepted and normalized to fr-CH / de-CH.
#
# domains.conf is the source of truth for both lang and locale.
