* Feature: Allow configuring the compression type and compression levels during export

Building on the zip export improvements, this now allows users to further configure the
zip to fit their needs.  A simple stored zip for speed, or a high compression zstd for
the smallest archive.  Full validation of the method and levels at the command line

 in the target directory, named according to the current local date or the
 value set in `-zn` or `--zip-name`.
 
+The compression method for the zip can be set with `--zip-compression`
+(`stored`, `deflated` (default), `bzip2`, `lzma`, or `zstd`) and tuned with
+`--zip-compression-level` (deflated: 0–9, bzip2: 1–9, zstd: -22–22; ignored
+for `stored` and `lzma`). Both options require `--zip`.
+
+!!! warning
+
+    `zstd` compression requires Python 3.14 or newer on **both** the machine
+    creating the export and any machine importing it. An archive compressed with
+    `zstd` (or `lzma`/`bzip2` where those modules are unavailable) cannot be
+    imported on a runtime that lacks the codec; the importer will refuse it with
+    a clear error. The default `deflated` is universally readable.
+
 If `--data-only` is provided, only the database will be exported. This option is intended
 to facilitate database upgrades without needing to clean documents and thumbnails from the media directory.
