+`darwins_finches` and `wolf_sample` are small **curated subsets** drawn from the
+full `bioclip-2_float16` embeddings (stored under `demo_subset/`). They are meant
+for quick experiments, prototyping, and demos — for example the
+[Image Embedding Explorer](https://github.com/Imageomics/emb-explorer) demo —
