Banner
A full-width, fixed-identity notice. It stays pale yellow with dark ink in every theme, making it the right home for a persistent, machine-level message. Emphasize key words with <b>.
Default
A single ds-banner spans the width of its container; add the hidden attribute to dismiss it.
<div class="ds-banner">Settings <b>modified locally</b> on this machine — values differ from the shared reference. Use Settings → Reset to restore.</div>
