Audit 13.1 (t4 line 641): the banner rendered wifi_off in colorScheme.error (red) inside a generic glass card. Rebuilt using offlineAccent (#E8879A) — a token that existed since Tier 1 with no consumer — for the tint, border and icon, plus the prototype's title/ detail layout and a restyled Retry chip. New offlineBannerTitle key translated to all 13 locales.
