Offline presentation

Measurements should not depend on a connection.

The intended installed experience keeps core conversion tools and common unit definitions available after the first visit.

The instrument shell is ready.

Common converters, categories, favorites, and history would remain readable from local assets. Connection-dependent update checks wait quietly.

Service worker intentionally not included

This frontend-only delivery shows install, offline, cached, and update states. It does not register a service worker or cache application assets.

Keep the current measurement visible and explain what remains available.

Present a clear refresh action when a new frontend version is ready.

Offer installation without interrupting the primary conversion task.
