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.


Interest in Anchor positioning led recent activity with 7 new upvotes,  
reinforcing the steady momentum previously noted for CSS layout primitives.  
Top-tier requests such as JPEG XL and Temporal maintained their consistent  
upward trajectory, with JPEG XL now surpassing 400 total upvotes. Fresh  
signals emerged for Lazy-loading media and popover="hint" , including  
engagement from developers at companies like WPEngine and Accenture.  
Meanwhile, CSS logic and sizing features, including if() , @function , and  
Masonry , continue to receive stable, broad-based support, reflecting  
sustained demand for more expressive styling capabilities.
