/* Guide pages: the sidebar acts as a section switcher, so picking a topic shows
   that section on its own instead of one long scrolling page.

   Everything here is gated behind classes that guide-sections.js adds at runtime,
   so with JS unavailable the page still renders every section stacked as before -
   which also keeps the full text in the DOM for crawlers. */
