## Title

    Proposed fix: [pip] 'Cannot install build dependencies' (failed-build-dependency-install) — isolated build env can't fetch setuptools/wheel/other build-system.requires (offline --no-index, private ind

## Body

    Recommended action: Add the build backend wheels to the wheelhouse/mirror (`pip download setuptools wheel <backend>`), or prebuild wheels on a connected machine; alternatively use --no-build-isolation after installing build deps into the target env yourself.
    
    Option: Provide build backends offline [evidence: documented_workaround]
    Applies when: See record scope.
    Steps:
    1. On a connected host: pip download -d wheelhouse setuptools wheel <other build requires>
    2. Install with --no-index --find-links wheelhouse
    Expected: Command proceeds without the error.
