Pattern

Notifications and banners

Which surface carries which message: banners, toasts, notices and push.

Rules

Banners for department load, offline, stale, paused and maintenance: full width, one sentence, never glass, never fixed.
Toasts only confirm ("Request sent"); never for errors that need action.
Push and text messages never contain health information; they bring the person back to the app.
Live regions are polite, except the urgent "I feel worse" confirmation.

It's busier than usual today. Waits may be longer.

Banner · Department load, offline, stale, paused, maintenance and announcements.

4 s · 8 s with an action

Translated by machine. Ask staff if anything is unclear.

…

Machine-translation badge · Says a page is machine translated and offers the original.

Code delay notice · Why care is delayed during a critical event, without alarming anyone.
