# Prebuilt V8
# -----------
# Building V8 from source takes 10+ minutes. `make download-v8` fetches the
# matching prebuilt archive from the zig-v8-fork releases instead; build.zig
# discovers the cached files itself, so the target only fetches. The versions
# are read from the install action so they can't drift from CI.
#
# The cache path is keyed on ZIG_V8_TAG as well as the archive name: a
# zig-v8-fork release keeps the same asset filename across tags (the name
# encodes only the V8 version), so a tag bump that leaves V8_VERSION alone
# still ships different bytes. Keying the cache on the filename alone made
# download-v8's `test -f` guard skip that refresh and leave a stale archive
# in place, which then fails at link time on undefined v8__* symbols.

# already keys freshness.
