Which strategy will Discloud adopt for ARIA live regions in real-time log updates?

The Discloud dashboard currently updates log panels via DOM changes that are not announced to assistive technologies, leaving screen‑reader users unaware of new entries.

Implementing ARIA live regions would convey these updates, but the team must decide whether to use polite or assertive modes, scope the regions to individual log containers or a single global region, and throttle updates to prevent verbosity.

What live‑region mode best balances timeliness and verbosity for log streams, and how should Discloud scope the regions to avoid overwhelming users while ensuring critical errors are announced promptly?
