   Session view (/dashboard/sessions/<id>), 2026-11-07. Browser Use's
   run view, Browsa's brand: a chat column (user bubbles, a collapsible
   "Worked for 13s" step timeline, the answer, a follow-up composer) and
   a right panel with the live browser in a drawn browser frame, Files
   and Recording. Rendered by renderSessionPage() in app.js. Theme tokens
   only, so light (default) and dark both work.
