   ArbZG retrieval — "instrument & document"

   Two material registers, and the distinction carries meaning:
     paper  — the law and the answer. Warm ground, serif, long measure.
     plate  — the retrieval machinery. Dark inset, mono, plotted.

   Two data colours, used nowhere decoratively:
     --dense  slate blue   = bi-encoder / cosine similarity
     --ce     vermilion    = cross-encoder / joint relevance
