+  batch of 20-MP+ photos. On a 2 GB VPS that's enough to OOM-kill the

+  hosts](#low-memory-hosts) below for the recipe to run on 2 GB).

+### Low-memory hosts
+
+Running on 2 GB RAM (e.g. an entry-level VPS) is workable but requires
+tuning the upload-processor concurrency down. The backend auto-detects
+total RAM at startup via `os.totalmem()` — on a host that reports < 3 GB,
+it defaults `UPLOAD_PROCESSOR_CONCURRENCY` to **1** instead of 2 and logs
+a one-shot warning. You can pin the value explicitly in `.env`:
+
+```env
+# Single worker loop — slower batch processing, lower peak RSS
+UPLOAD_PROCESSOR_CONCURRENCY=1
+```
+
+The trade-off is throughput: a single worker processes one photo at a
+time, so a 100-photo batch takes ~2× as long but won't OOM. **Health-check
+note**: if the backend dies under memory pressure, the gallery serves
+`503 Service Unavailable` on thumbnails until Docker's
+`restart: unless-stopped` brings the container back. Persistent 503s
+during/after an upload batch on a low-memory host are almost always this.

+ * exportAsTxt — issue #623 regression test.

+ * The admin UI labels the TXT export "for Lightroom search". Lightroom's
+ * filename search wants ONE comma-separated line WITHOUT file extensions
+ * (the gallery JPEGs may map to RAW files in the catalog). The frontend
+ * now passes separator='comma' + include_extension=false for the TXT
