+# dots-themes-fetch.sh — download the third-party theme files this repo's configs use but the
+# repo doesn't ship. Each host fetches its own copy from upstream, so the repo redistributes
+# nothing and needs no licence notice. (Same idea as bin/dots-icons-link.sh, which links Tela's
+# icons from the host instead of shipping them.)
+#
+# Every entry is pinned to an upstream commit plus a sha256, so a fetch is exactly the file
+# that was reviewed. To update one: bump the commit in the URL, check the diff, then replace
+# the checksum with `curl -fsSL <url> | sha256sum`.
+#
+# Usage: bin/dots-themes-fetch.sh [-n]   (-n = dry run). Idempotent; ./install.sh runs it on
+# every host. A destination that's already a real file is left alone, even if its content
+# differs (a local edit wins). A symlink there (e.g. the stow link left dangling after the
+# repo dropped the file) is replaced: mv swaps the link itself, never writes through it.
+# Exit 1 if a download or checksum failed; the app then falls back to its built-in theme, so
+# install.sh only warns.
