   FastUTM articles and guide hub (v1.7.0)
   Loaded only through $extra_css = ['article'] on /guide/ PHP pages.
   Every selector starts with .fu-article or .fu-hub, so nothing here can
   reach the tools. Fonts are inherited (not set here), so the site's
   dyslexia-friendly mode still switches the typeface on these pages.
