AlertKind

AlertKind is the severity enum used by Alert.

It answers a product question, not only a color question: what kind of message is this? A good alert kind helps people judge urgency before they read every word.

Example

use fission::prelude::*;

let node = Alert {
    kind: AlertKind::Warning,
    title: "Storage almost full".into(),
    description: Some("Uploads may fail until space is cleared.".into()),
}
.build(ctx, view);

Choice table

Choice	Type	Meaning	Notes / default behavior
Info	AlertKind	Informational message.	Good for neutral guidance or status updates.
Warning	AlertKind	Potential problem that needs attention soon.	Good when the user should notice risk before failure.
Error	AlertKind	Something failed or is invalid right now.	Use when the user needs to recover or change input.
Success	AlertKind	Positive confirmation that something worked.	Best for meaningful success, not every tiny action.

Specific advice

Pick the kind based on product meaning, not aesthetics. If everything becomes a warning just because orange looks noticeable, users lose trust in the severity system.
