This is an automated email summarizing recent activity on the  
developer-signals repo, which is where web developers add their support for  
web features that are not yet implemented in all major browsers.


Momentum for JPEG XL continues with new upvotes from developers at  
Microsoft, maintaining its status as a top-priority request following  
previous trends. Steady interest persists for UI and logic primitives, with  
Customizable <select> , Temporal , and corner-shape continuing to  
accumulate baseline support. Technical feedback for contrast-color()  
highlighted its critical utility in data visualization, specifically as a  
performance-efficient companion to color-mix that eliminates the need for  
expensive computed color resolution in JS. Incremental activity also  
focused on layout and styling refinements, with text-box and Anchor  
position container queries receiving modest gains.
