The throughline today is reliability over features, with one high-impact crash-reporting fix and a push to lock in visual edge cases with reproducers.

First, Hermes fatal errors on the New Architecture, in PR 59729. On the legacy path, a fatal handler logs the reason and records it as the abort message. On the New Architecture, nothing installed it, so the reason went to standard error, never reached Android logs, and the process died with a bare segmentation…

Second, rendering edge cases getting test coverage. PR 59726 adds a tester example for transform origin with decimal and negative strings, after the old parser mangled values like 52.9 percent and negative pixel offsets, and threw on mixed keyword values. Separately, PR 59732 adds an iOS playground reproducer for…

Finally, two maintenance fixes.
