+      `ppy.osu.Framework 2026.520.1` was compiled against. This version is the only
       one whose `runtimes/android-arm64/native/libveldrid-spirv.so` is aligned to 16 KB
       pages (required by Android 16+). It lives only as a release asset on
       <https://github.com/winnerspiros/veldrid-spirv/releases/tag/1.0> and is vendored
       under `local-packages/` (see `local-packages/README.md`). Without this pin NuGet
       would silently fall back to the 4 KB-aligned nuget.org build and emit NU1903.
