on-settle: increase wait from 2s to 4s — server fetch + settle hook needs more time than the original timeout allowed. server-signals: add actual cross-island signal test — click a price button in writer island and verify reader island updates. view-transform: fetch catalog before toggling view — the view toggle only changes rendering of loaded items, not the empty state. All 19 demo-interaction tests pass (was 14/19). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
