/* The Instruments page (issues #290, #297). The site's own colours
   (website/style.scss): ink #1f1e1b, muted #52514e / #898781, rules #e1e0d9,
   link #1c5cab, panels #f9f8f4. Controls use system-ui; headings keep the
   site's serif (Palatino).

   Colours, so that one means the same thing everywhere:
   - a collection has the site's categorical colour (laws #2a78d6, regulations
     #008300, guidelines #e87ba4, treaties #eda100), as on the Atlas;
   - a compared excerpt is marked by a quiet grey rule and a small "Compared" label,
     and nothing else in the document is coloured. */
