/**
 * Shared binary-unit byte formatter for the build/verify scripts.
 *
 * The Lambda ZIP-size budget is in mebibytes (Lambda's 250 MB / 248 MiB
 * gate is binary, not decimal), so logs and CI failure messages use
 * KiB / MiB / GiB. This is intentionally a different unit system from
 * `packages/cli/src/ui/format.ts`'s `formatBytes` (KB / MB, decimal) —
 * don't conflate them.
