    • ⚡️ Updated: Redesigned the custom checkboxes and radios for more obvious states.

    • ⚡️ Updated: Changed auto columns (e.g., .col-auto) from max-width: none to max-width: 100% to prevent content from causing a column to overflow the parent.
    • ⚡️ Updated: Improved rendering of custom selects, ranges, file input, and more.
