// R-606 (v0.264.0) — every sentence of the update path reaches the page in the READER's language, on
// BOTH pages that carry it (the app page and the apps list): the phase label, the update error and the
// hold sentence. Asserted both ways — the English present AND the Hungarian gone — because a page
// carrying both would pass a presence check (the composed-sentence class, R-573/R-590/R-596/R-598).
//
// COMPANION RED-PROOF (REPORT.md): make localeFuncs' updateErrorText return .UpdateError — the English
// page carries the Hungarian sentence and this test fails.
