The Driver's first laptop run with DX_SYNC_REMOTE: when main moved the page went
white. A landing rewrites dozens of built leaf index.html files under public/, and
Vite answers each changed .html with a full page reload (measured: one edited leaf
page, one full-reload broadcast), so a pull fired a burst of reloads while git was
still writing. The dev server no longer watches public/, which it never serves
through its module graph (measured after: no reload). Rudder's corner pill also
grew with every streamed word; while recording it is now 300px wide and shows the
newest words, cut from the front.
