+#   ICCERY_RELEASE_TAG      release tag / describe string stamped into the
+#                           bundle's ICCeryReleaseTag Info.plist key and shown
+#                           in the About dialog.
+#   MARKETING_VERSION       CFBundleShortVersionString — strict X.Y.Z only
+#                           (Apple forbids suffixes; tag payload never lands here).
+#   CURRENT_PROJECT_VERSION CFBundleVersion — monotonically increasing integer.
+#                           macOS/App-Store convention: never reset per version.
+#
+# Resolution:
+#   RELEASE_TAG env matching 'v[0-9]*' wins (CI tag builds; branch pushes pass
+#   the branch name and are ignored). Otherwise `git describe` on the worktree.
+#   Marketing version = first three numeric components of the tag core; a tag
+#   with no numeric core falls back to project.yml's MARKETING_VERSION.
+#   Build number = BUILD_NUMBER env override, else `git rev-list --count HEAD`.
+#
+# Hard fails (release-tag builds only): tag core not 1-3 numeric components,
+# or parsed X.Y.Z != project.yml MARKETING_VERSION — bump project.yml or fix
+# the tag before packaging.
