Updated the homepage layout by replacing the row of three cards with three full-width sections to improve content presentation and readability.

Updated public documentation to direct users to the new editing page on the operations site and removed references to retired operations artifacts.

Updated the project documentation to record recent contrast fixes, artifact decisions, and replaced the outdated operations board section.
