/* The Institute — the evidence shelf.
   Same two hues as site/index.html, and they still mean what they mean there.
   INDIGO is the standard: what we assert, and what an entry entitles us to say.
   RUST is the consequence: every place something costs us. Here that is the
   limits and the refusals — which is the right reading, because a stated limit
   is a claim given up. */
