@kinqsradio Ready for review: the Ledger composer/details-rail fix is green on 889e042. All eight E2E shards, Web, preview, CodeQL and contribution checks passed. Independent Codex review and Light/Dark/Dim inspection are complete. This addresses the reproduced current Ledger case in #272; the original packaged macOS symptom remains unverified.

Reviewed the diff against current main; the change is scoped and the checks are green. Merging with a merge commit.
