+# chromium-widevine-helper-bin - prebuilt package of
+# https://github.com/GloriousEggroll/chromium-widevine-helper
+# (Chromium extension + native messaging helper that installs Google's
+# Widevine CDM into Chromium-based browser profiles).

+# Upstream publishes neither releases nor tags; the canonical version lives in
+# the Fedora RPM spec on the main branch. build_artifact() snapshots main,
+# verifies the snapshot still carries the requested version and assembles the
+# install tree following upstream's spec - with Fedora's /usr/libexec
+# relocated to /usr/lib, which Arch uses instead.
