Alert Banner generator
Unlike a toast, an alert banner is persistent — trial expiry notices, maintenance windows, and validation summaries all belong here. Style it clearly enough to notice, without visually dominating the page.
Your changes autosave in this browser, and the link above reproduces this exact configuration for anyone you send it to.

- Reserve red/error banners for genuine blockers; overusing them trains users to ignore all banners.
- Always make dismissible banners actually closable — a banner that cannot be dismissed feels broken, not urgent.
- Keep the message to one sentence with a single, clear next action if one is needed.
