 * #14752: `settings.proxySubscription.selectorHelp` is rendered by SubscriptionTab
 * through a plain `t()` call, so next-intl compiles it as an ICU message. A bare
 * `<name>` parses as an unclosed rich-text tag and the help line falls back to the
 * raw key. The placeholder must be ICU-escaped (`'<name>'`) so it renders literally.
 * Same class as #12302 / #12505.
