The About logo now actually renders on managed installs. bb's builder has no image loader and serves only the built app.js/app.css, so the previous runtime ./assets/*.png URL always 404'd outside a local checkout. The mark is now a 512 px asset served lazily as a data URI over a new aboutLogo RPC (memoized, null-safe with a text fallback), keeping the board bundles untouched. The dead dist/assets postbuild copy is gone; tests/about-logo.test.mjs locks the delivery contract, the asset budget, and the ban on runtime static-asset URLs.
