feat(speakers-teaser): randomize home wall order each load#230
Merged
Conversation
The home-page speakers teaser ordered the roster by `order` and always
opened on the same first four names, so repeat visitors saw an identical
lineup every time. Shuffle a copy of the roster (Fisher-Yates) client-side
so the starting window — and the rotation sequence — is random per load.
The Firestore query keeps `orderBy('order')` for a stable fetch; the
shuffle is memoized on the speaker id set so it only reshuffles when the
roster actually changes, not on every re-render or rotation tick. Reduced-
motion and small-roster visitors also get a random set rather than a fixed
one.

Summary
The home-page speakers teaser (
SpeakersTeaser.tsx) rendered the roster ordered byorderand always opened on the same first four names. Repeat visitors saw an identical lineup on every load. This shuffles a copy of the roster client-side so the starting window — and the rotation sequence — is random each load.Why
Requested: the home speakers panel should always start random so the list isn't the same on start.
Behavior
orderBy('order')for a stable fetch — only the display order is shuffled.Files
