// ALEF_MOCK_ALT_HOST from its own process environment, so the standalone spawn
// here sets it explicitly rather than relying on an ambient shell var.
// The map starts from the build runner's own environment (`b.graph.environ_map`; the
// pre-0.16 process-level env-map getter no longer exists), so an already-exported
// override still wins. Measured on Zig 0.16.0 and 0.17.0. ~keep
