Main merged in at tip 0598d49d. Main had moved twice, so the merge is against 50f1a9be, not ae23131c. No conflicts.
Catalogues: all ten come out at 1938 keys, each carrying both this branch's three reaction strings and main's nine `multi_device_blossom_*`. CHANGELOG: both bullets inside [Unreleased], main's Blossom one and this one.
Gate re-run whole at the merged tip: `:ui:jvmTest` and both app compiles green; `:app-core:jvmTest` green; the wasm suites of app-core, ui and app-web green; `:app-web:e2e` 48 + 152 checks.
