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.


Steady interest persists for core layout and UI primitives, with  
corner-shape , Anchor positioning , and text-box continuing to build on  
previous momentum. Notably, Scoped custom element registries experienced a  
significant uptick in relative activity this period, receiving new support  
from developers at companies such as Aquera. Specialized capabilities also  
drew focused interest, with WebNN receiving backing from Intel Corporation  
and overflow-anchor seeing a relative surge in upvotes from OpenTeams AI.  
High-priority items including JPEG XL , Temporal , and Customizable  
<select> maintained their baseline trajectory with incremental gains,  
reinforcing their status as top-tier community requests.
