/* Widen Furo's right "On this page" TOC sidebar so long class names like
   rfgen.scene.DefaultSceneComposer don't wrap mid-word.

   Furo hardcodes `.toc-drawer { width: 15em }` in its compiled CSS
   (not a CSS variable), and collapses the drawer off-canvas at viewports
   < 82em, so width overrides only show at wide viewports. We do two
   things:

   1. Bump the drawer to 22em and shift its off-canvas hidden position
      to match (right: -22em).
   2. Allow long inline-code class names (rfgen.scene.DefaultSceneComposer)
      to break at dots / hyphens rather than mid-word, as a safety net.

/* At wide viewports, keep the no-toc placeholder in the flex row as an
   invisible spacer so article content is left-aligned consistently.
   Furo sets display:none on .toc-drawer.no-toc, which removes the element
   from the flex row and shifts the content column rightward relative to
   pages that do have a right TOC. Overriding to visibility:hidden at
   wide viewports preserves the column width without showing any content. */
