The #718 keyboard-tab-order test hardcoded the visual order
['Eugenie','Walter','Clara','Hans'] on the assumption that buildLayout
sorts each generation alphabetically. #724 replaced that with the
tidy-tree layout, which orders a couple's run by structural ownership
(earliest birth year, then a deterministic id tie-break) — so Walter
(id …a1) now owns the run and Eugenie renders to his right.
Both PRs were green independently; the stale assertion only surfaced
once #718 and #724 landed together on main. Correct the expected reading
order to ['Walter','Eugenie','Clara','Hans'] and refresh the now-wrong
'alphabetical' comment. The companion self-validating test (DOM order ==
sorted by y,x) already guarded the real property, so only the hardcoded
assertion needed updating.
