Snackbar Item
A single toast: variant color, leading icon, message, and optional action and dismiss buttons. It emits action and dismiss. Usually managed by esa-snackbar-container, but it renders standalone too.

Add an action label, or set dismissable={false} for a toast that cannot be manually closed.

Accessibility
- The dismiss button carries an
aria-label="Dismiss"; the leading icon is decorative (aria-hidden). - Variant color is paired with a distinct icon, so meaning is not conveyed by color alone.
- When used standalone, announce the message in a live region appropriate to its urgency.
Theming surface
Every public token this component reads, extracted from its source at build time.
The Resolves to column walks each token's real lineage —
component → semantic → primitive → raw value — so you
can see exactly where re-pointing it lands. A spoke re-skins by overriding these in
its theme-<slug>.css; component internals are never edited. No
hook for what you need? File it with /request-lego.
