Accessibility

What the library guarantees:

• Focus moves into the card on open and goes back to the triggering element when you exit.
• Everything except the card is inert, meaning untabbable, unclickable, and hidden from screen readers. In interactive mode the spotlighted target is exempt too. No keydown interception, no sentinel nodes.
• The step counter is part of the card’s accessible name, so it reads as “Step 2 of 5, Invite your team” in one go and doesn’t arrive as a separate interruption. If focus is already inside the card, step changes route through a polite live region so nothing gets announced twice.
• Escape always exits, from anywhere, even while focus is on the target.
• aria-modal is set only in fully blocking mode.
• Every animation collapses under prefers-reduced-motion.

The parts that are still on you.

Write step text that makes sense read aloud without the visual spotlight. “The button below” means nothing to a screen-reader user. Give every target an accessible name. And if a step teaches a drag interaction, give people a keyboard path to the same outcome.

No library can make your integration conformant. All it can do is stop being the reason it isn’t.
