# ---------------------------------------------------------------------------
# zig for aarch64 ONLY - repackages upstream's official, signed, statically
# linked prebuilt release (ziglang.org/download), to unblock ghostty there.
#
# Why: EPEL10 ships zig + zig-rpm-macros for x86_64 only. Building zig from
# source on EL10 aarch64 is blocked (EPEL's llvm20 lacks targets zig needs;
# see git history of this spec and SETUP.md step 28 for the three source-build
# attempts). Upstream's prebuilt Linux binaries are fully static (no LLVM or
# libc runtime deps), so repackaging them sidesteps that entirely.
#
# x86_64 is intentionally excluded: it keeps consuming EPEL's own zig 0.15.2.
#
# Verification: the tarball's minisign signature is checked in %%prep against
# the ziglang.org release key, plus the SHA-256 from ziglang.org's
# download/index.json.
