Pull request overview

This PR aims to improve Playwright VRT snapshot reliability by enforcing reduced motion by default and ensuring Storybook pages wait for fonts to load before screenshots are taken.

Changes:

• Sets reduced motion globally in the Playwright test configuration.
• Updates the Storybook visit helper to wait for document.fonts.ready before continuing.
• Removes redundant per-test reduced motion media emulation calls.
