shape() entering the main branch is a small milestone in the history of typesetting; let's see whether Safari follows at Interop 2026.

ego announces that the shape() contributed to Chromium has been merged into the main branch, and Chrome 149 will globally roll out this feature. It only requires a single line of CSS to wrap text along any Bezier curve, completely replacing existing JavaScript layout methods. Previously, shape-outside only supported five basic shapes; this time, allowing the browser's rendering layer to directly handle curved layouts significantly reduces overhead. A proposal has been submitted to Interop 2026, calling for Safari and Firefox to follow suit.
