+// Real vue-i18n instance (unlike ReceiveBitcoinModal.test.ts, which mocks
+// `t` to a no-op and so cannot catch a bad message string). Operator report
+// (2026-09-08): clicking the Ecash tab closed the whole Receive modal, in
+// both the browser and the Android companion's WebView. Root cause: vue-i18n
+// treats a bare `@` as the start of "linked message" syntax — `en.json`'s
+// `receiveBitcoin.lnAddressLabel` ("Your @minibits.cash address:") isn't
+// valid linked-message syntax, so *compiling* that message throws a
+// SyntaxError the instant it's first rendered (i.e. the moment the address
+// loads), and the uncaught render-function error blanks the whole teleported
+// modal. Fixed by escaping it as `{'@'}` (the same pattern already used for
+// `settings.domainNamePlaceholder`). This test uses the real compiler so a
+// future bad interpolation string in this component fails fast in `npm test`
+// instead of only in a live browser.
