/**
 * Shared styling for the Resolume plugin demos.
 *
 * Dark, because that is what these effects are looked at in and because a
 * picture with real blacks in it needs somewhere dark to sit. The inspector on
 * the right is laid out the way a host's parameter panel is — name on the left,
 * control and value on the right, grouped under headings — but it deliberately
 * does not imitate Resolume's own chrome. It is a stand-in for the host's
 * inspector, and a page that looked like a screenshot of Arena would be
 * claiming to be something it is not.
 *
 * No colour variables from the website: these pages are their own thing and the
 * navy is used only for the frame. `--sw-support-accent` is read by the shared
 * support footer.
