Auditing Big Picture for goal (d) I read this as a live defect: big-picture threads the host's locale into
each child's profile-config as `lang`, while the grid's prop is `languageCode`. On a profile-config embed
that would leave a composed grid in the wrong language — exactly the failure 8b40f6c58 was written to fix.
It is not a defect. people-groups-grid.vue accepts three spellings — languageCode || locale || lang — and
`lang` is the third. Two greps settled it, and the near-miss is the point: nothing at either end said so.
Both ends now do. The writer records that the spelling is load-bearing and which fallback it lands on; the
reader records that `lang` has a caller and why that caller cannot reach it any other way — getRuntimeLocale
is module state, and a separately-built child bundle gets its own copy, so threading the config is the only
channel big-picture has.
★ WHY A COMMENT AND NOT A GATE. The failure is invisible in the obvious place: ?lang= embeds keep working,
because the grid falls through to localeFromUrl(). Only a host passing profile-config sees it, which is the
smaller and quieter half of the traffic. A gate for that would have to stand up a composed embed with a
profile-config locale and read rendered text — which is rega's browser run, not a headless check — so the
honest guard is to make the coupling legible to whoever next tidies either list.
No behaviour change. Verified: check:sfc-parse PASS.
