Site / build (pull_request) Successful in 9s
security.txt (RFC 9116) under .well-known with the mailbox as contact and an expiry in September 2027. robots.txt allows everything and points to the sitemap. The pixel 9 gets a favicon.ico (32 and 48 px) and an apple-touch-icon.png, drawn by tools/make_favicons.py from the same rectangles as favicon.svg.
