/* =========================================================
   Growing Minds Science: guide.css
   The guides under /tools/ on the annotated-observation system (body.gpage).
   Primitives from fg-base.css, the decoder and gms-tools controls from
   tools.css, the close band from hubs.css. Each guide keeps its own markup
   and gms-tools.js hooks; this file gives those components the system's
   look: one narrow column, sage-mist panels, quiet rules between rows,
   choices as calm outlined buttons, sources in the research-blue module.
