Alpha checklist updated with enhanced accessibility and clearer guidance

We have released an update to the preliminary alpha checklist on the Clarvia website (/checklist), focusing on accessibility standards and plain-language communication. The update introduces refined ARIA attributes, improved keyboard navigation, and enhanced contrast across interactive checklist items. In addition, the introductory sections and guidance notes have undergone a plain-language pass to ensure complex administrative procedures and legal requirements are simple and stress-free to understand. These updates help ensure that our dynamic consequence graph remains fully usable across all devices and assistive technologies as we continue expanding our coverage of European jurisdictions.
