Consolidated handoff added to the Partial Order Handling section: the bugs
that only live tablet testing surfaced (phantom stage cards, scan-button
icons/labels, dark-mode undefined --bs-* vars, from-step predecessor block,
seeded-stage auto-finish on drain, gating fall-forward) and the open items
(discoverability badges, Scrap/Rework standalone buttons, automated tests
not written, dark-mode chip polish). Docs only.
