# Tools come from the DotSlash files in scripts/, so the build depends on
# pinned upstream releases rather than whatever the host happens to have. The
# prelude's system toolchains resolve their tools through PATH, so buck2 must
# be invoked with scripts/ prepended — see the `buck` recipe in justfile.
#
# This is the same arrangement .cargo/config.toml used to describe: zig cc
# carries its own glibc sysroot, which is why this repo builds on a machine
# with no `cc` at all. Unlike vidya there is no Android row here — both shared
# objects this repo ships are desktop, and the APK takes its libvidya from
# vidya's own buck2 build.
