Products.ts's admin.livePreview (added earlier this session) only made
the admin UI show a preview iframe — the actual page had no mechanism
to receive postMessage updates and re-render with unsaved draft data,
unlike Pages/Posts which already have this (LivePageContent.tsx/
LivePostContent.tsx). Edits in the backend were invisible in the
preview until an actual save (reported 2026-08-30).
New LiveProductContent.tsx mirrors LivePageContent.tsx's pattern
exactly: useLivePreview<PayloadProduct> + mapPayloadProduct, rendering
via ProductBlocks.tsx's now-exported renderProductBlock (sync) instead
of the full async ProductBlocks wrapper. testimonialsRef/crossSell
skipped in the live subset (need an async fetch a client component
can't perform inline) — same "editable subset only" scope Pages/Posts
already accept. shipping/tax/Kleinunternehmer context is fetched once
via the newly-exported getProductBlockContext() and passed in rather
than re-fetched per keystroke.
/der-eine and /tasse-die-pause now check draftMode() and swap in
LiveProductContent instead of the normal async ProductBlocks when
Payload's Live Preview iframe has it enabled.
