   Growing Minds Science: article.css
   The eight articles on the annotated-observation system (body.art).
   Primitives from fg-base.css; the close band from hubs.css. A title block
   with the short version on sage mist, then one reading column with the
   contents beside it. Figures sit on soft white with calm corners;
   sources sit in the research-blue module. Tokens from
   tokens-field-guide.css.
