An uploaded image's favicon now carries the stone mark like the PWA icons and is cut to a circle. The mark is larger on the favicon and on the regular (rounded-square) icons, and the settings preview matches. A render revision in the set's version gives re-saved icons a new URL past the immutable cache. Co-Authored-By: Claude Opus 5.5 <[email protected]>
