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.


Ongoing interest in performance and security primitives persists as both  
Lazy-loading media and the Sanitizer API continued their steady growth  
trends this period. The Temporal proposal also picked up three new upvotes,  
cementing its position as one of the backlog's most anticipated APIs with  
166 total signals. Elsewhere, the BBC signaled support for the <meta  
name="text-scale"> proposal, highlighting a continued developer focus on  
accessible viewport scaling. Finally, new developer feedback on Column  
breaks illustrated the difficulty of simulating real-time EPUB rendering in  
the browser due to the lack of Safari and Firefox support for break-after:  
column .
