+- **The gateway embeds the documents `llmgw-kb` sends.** A document may be sent as its passages' text alone; the
+  gateway embeds them through its own `/v1/embeddings` as the caller, 32 at a time and four batches at once,
+  waiting out a busy engine rather than failing the document. About a kilobyte a passage leaves the machine instead
+  of a vector down and up again, some thirty times more. `llmgw-kb` does so with a gateway that says it can
+  (`server_embeds` in a collection's answer); `--embed-here` keeps the old way.
