+#### Visual identity for the gp-sphinx docs site
+
+The gp-sphinx docs site at <https://gp-sphinx.git-pull.com/> now
+ships the standard tony/* logo, favicon, and PWA icon set. The Furo
+sidebar shows light and dark logo variants, the browser tab carries
+a proper favicon, and a web-app manifest advertises the icon sizes
+for Android, Apple, and Microsoft platforms. (#41)
