/* help.css — the look of every help page (site/help/*.html). Same colours as the site (common.css); built for reading.
   A page is opened two ways: on its own (/help/levels.html — a slim bar on top) and inside the ❓ drawer of the page it
   explains (help.js puts class "in" on <html>, which hides the bar). */
