This plugin fetches emergency alerts from a Common Alerting Protocol (CAP) XML feed and displays them across all sites in a multisite network. It is designed for educational institutions or organizations that need to broadcast urgent notifications like campus closures or safety warnings to their entire web presence.

• CAP Feed Integration: Connects directly to a CAP XML feed, the standard for public alerting, to automatically pull in active emergency messages.
• Network-Wide Display: Once activated at the network level, the plugin shows alerts on every site within the multisite installation, ensuring consistent messaging.
• Performance-Optimized Caching: Uses server-side cron jobs and transients to poll the external feed every 60 seconds, significantly reducing load on both the alert feed and the web server while aiming to disseminate alerts within 120 seconds.
• Optional Message Archiving: Can be configured to automatically create a post or custom post type on a designated site within the network, creating a permanent record of all issued alerts.
• Manual Override Capability: Includes settings to enable a manually entered message, allowing administrators to post custom alerts directly through the plugin's configuration panel when needed.
