Summary
Front End Previews that behave like production—same runtime, slimmer asset syncs, and faster iteration for stakeholder review and QA.

Redesigned preview environments to behave like production without the wait. Previews run on the same rendering stack as prod, and asset syncs are optimized to cut iteration time.

Highlights

  • Uses the framework’s standalone output to run previews consistently
  • Speeds up asset syncing by excluding heavy, unnecessary directories
  • Treats each preview as a versioned app instance for reliable behavior
