// Every message string must survive vue-i18n's message compiler. Found the
|
||
|
|
// hard way (2026-09-08): a bare `@` in a message is parsed as the start of
|
||
|
|
// "linked message" syntax (`@:key`), so a literal `@` (an email/handle-style
|
||
|
|
// placeholder, e.g. "user@example.com") throws a SyntaxError the first time
|
||
|
|
// it's *rendered*, not at build time — see [[vue-i18n-bare-at-sign-crash]]
|
||
|
|
// in project memory for the full incident (it blanked a whole modal in both
|
||
|
|
// the browser and the Android companion's WebView). A literal `@`, `{`, `}`
|
||
|
|
// or other message-syntax character must be escaped as e.g. `{'@'}`.
|
||
|
|
//
|
||
|
|
// This walks every string in every locale file and asks the real compiler
|
||
|
|
// to parse it — no rendering, no component needed, so it's fast and catches
|
||
|
|
// the whole class of bug regardless of which component ever ends up using
|
||
|
|
// the string.
