Type of Change

• Refactor / maintainability improvement

Testing

• Full workspace type checks, lint, repository audits (including import and API validation), generators and docs checks pass.

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.

Before / after visual comparison

Browser Back/Forward controls share BrowserToolbarButton, preserving the 30px treatment and disabled appearance.

Left = before; right = after.

Rendered component fixtures with application CSS and local data, rather than authenticated product-page screenshots. These are representative visual examples, not end-to-end behavior coverage.
