  <!--
    Reproducible-build defaults applied to every project in the solution.

    The set below produces byte-identical pack output when the source tree
    and toolchain version match: deterministic compile, embedded source
    paths normalized via PathMap, SourceLink metadata, and CI-build hints
    that suppress timestamp embedding.

    Source Link (via Microsoft.SourceLink.GitHub) lets debuggers and
    decompilers fetch the exact source files corresponding to the
    shipped IL, which complements the SLSA provenance attached to
    release artifacts.

    SuppressNETCoreSdkPreviewMessage is set so a preview SDK doesn't
    inject a warning that affects determinism diagnostics.
