# The image is published for linux/amd64 and linux/arm64. Only the runtime
# stage is built for the target platform. The frontend and the .NET publish
# run on the build machine's own platform ($BUILDPLATFORM): the Angular bundle
# is the same on every platform, and `dotnet publish -a` cross-compiles for the
# target. So a multi-platform build emulates nothing but the apt install below.

# amd64 or arm64, set by BuildKit from --platform. `dotnet -a` accepts both
# names. Publishing for one runtime keeps only that platform's native
# libraries (libvips, SQLite) instead of all twenty-odd platforms' copies.
