+Install fetches item files as UTF-8 text, so 22 binary files (preview
+images/videos, the woff2 fonts of the two video-template skills) are excluded
+from every item's file list and never install. They remain in the repo for
+provenance. The two video templates degrade to fallback fonts for those
+typefaces after install.
