/* W Linux documentation site — one stylesheet for the offline copy and the web.
 *
 * Every colour, radius and font is a custom property. The values below are the
 * default theme `w`; on a W machine the Help window's profile overrides them
 * with the CURRENT theme (w-style axis `help` → userContent.css), so the page
 * follows the desktop without this file knowing any theme. Keep every visual
 * decision behind a variable for exactly that reason. */
