Emergency Banner

The emergency banner is a full-width strip shown at the top of every tenant and landlord dashboard — useful for announcing an incident or scheduled maintenance. It is platform-wide: one message, read the same everywhere. It appears only in the dashboard, never on a reader-facing site.

Only super admins can set it. From the Allegro Admin, open Settings → Banner:

Field	What it does
Enabled	Turns the banner on or off. A message is required while it is on.
Message	The text shown in the banner (up to 300 characters).
Details link	An optional http or https URL. When set, the banner shows a View details link that opens in a new tab.

Changes apply immediately across the whole installation — no deploy or cache-clear. Each person can dismiss the banner, and it stays hidden for them until the message or link changes, at which point it reappears.

The on/off state is the Emergency banner platform feature flag; see Feature Flags for how platform-wide flags work.
