Seeded specs reload the app many times, and each load through the Vite dev server evaluates ~315 unbundled modules (~4.6 s warm) versus ~13 bundled files (~0.4 s) from a production build. That load cost pushed operations-acceptance tests past the 30 s timeout in CI. Add an opt-in E2E_PRODUCTION_FRONTEND flag that runs vite build and vite preview (same port and /api proxy) and set it only for the seeded CI job. Mock specs stay on the dev server because some import /src modules in the browser. Locally, the full seeded suite passed 99/99 with no retries, and the previously timing-out test took ~7 s.

Description
Seeded E2E tests intermittently time out (example):
operations-acceptanceloads the page five times, and each Vite dev-server load takes 3–5 s.A new
E2E_PRODUCTION_FRONTENDflag serves the seeded job fromvite build+vite preview(~0.4 s loads), the bundle users actually get, which the analytics and paired-outcomes jobs already use. Mock specs keep the dev server since some import/srcmodules.Tests and Documentation
