+# Builds rusty_v8 from source inside the manylinux_2_28 containers and
+# publishes the static library + src binding as GitHub release assets.
+# The wheel CI consumes these via RUSTY_V8_ARCHIVE/RUSTY_V8_SRC_BINDING_PATH,
+# so V8 only needs to be compiled when the v8 crate version in Cargo.lock
+# changes (run this workflow manually after such a bump).
+#
+# Why from source: denoland's prebuilt archives require glibc >= 2.30
+# (e.g. pthread_cond_clockwait), but manylinux_2_28 wheels must link
+# against glibc 2.28.
