The PR appears safe to merge because the latest change resolves the prior props-interface requirement without introducing a type or behavioral regression.

Summary

This PR extracts shared browser toolbar button configuration into a reusable component while preserving existing navigation, menu-anchor, disabled-state, and download behavior.

• Centralizes the fixed button type, variant, size, and 30px geometry.
• Reuses the component for back, forward, reload, password-fill, and downloads actions.
• Updates the props declaration to the repository-required interface form.
