Theme Name: Specimen
Theme URI: https://schemarkup.com/
Author: schemarkup.com
Description: A laboratory theme for structured-data specimens. Each specimen page renders the content, the exact JSON-LD that ships in the head, and a dated evidence record of what search and AI engines did with it. The head markup and the on-page markup are generated from one source, so they cannot drift apart. Type marks and the collection graph are both computed from the data rather than drawn.

   One vocabulary. A state's colour means the same thing in a
   plate, a rail, a matrix cell and a timeline. Status hues come
   from a palette already validated for normal, deutan, protan
   and tritan vision at delta-E 10 or better between every pair.
