/* studio.css -- the browser-side cartogram page.

 * Everything is namespaced: --cs-* custom properties, .cs-scoped selectors,
 * cs-* ids. The host site already owns --ink, --line, --bg, .wrap and bare
 * h1/button/select rules, so nothing here may be defined on a bare element.
 * Written by hand -- an earlier attempt to namespace a stylesheet by regex
 * produced a parse error that silently killed the whole file.
