// R-574 — handler_debug.go's literals, classified once: 38 are PAGE COPY (every writeDebugJSON
// message/error, which debug.html prints into the result line, plus the pre-0.83 agent `notice`,
// which it prints into the log viewer) and were moved to the bundle (debug.api.*); ONE is PAYLOAD —
// the `Teszt esemény: %s (%s)` text handed to PushTestEventSync, which travels to the hub as the
// test event's own message — and stays a literal on purpose. The diagnostic dump carries no
// Hungarian.
//
// The consequence pinned here: the Hungarian page is byte-for-byte what it was (the parity gate
// proves the bundle text; this proves the handler reads it), and an English page is English.
// RED-PROOF (REPORT): put either producer back to its literal and the English rows fail.
