## Title

    Proposed fix: [Yarn Berry >= 3.1] YN0076 INCOMPATIBLE_ARCHITECTURE — package with os/cpu/libc fields not matching this system is not fetched, linked or built; direct platform-specific deps (e.g. @esbu

## Body

    Recommended action: Depend on the umbrella package (esbuild, sharp) instead of a platform-specific subpackage, and let optionalDependencies select the right one; when you need binaries for other targets (checked-in cache, Docker builds from host installs), set supportedArchitectures { os: [current, linux], cpu: [current, x64, arm64], libc: [current, glibc, musl] } in .yarnrc.yml and reinstall.
    
    Option: Use umbrella packages / supportedArchitectures [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. Remove direct deps on @scope/pkg-<os>-<arch>; depend on the main package
    2. If cross-arch artifacts are needed, in .yarnrc.yml: supportedArchitectures: {os: [current, linux], cpu: [current, x64, arm64]}
    3. yarn install
    Expected: Command proceeds without the error.
