 * FORCE TOC ALWAYS VISIBLE

 * sets inline styles (opacity:0, overflow:hidden, pointer-events:none)
 * on children of #quarto-margin-sidebar when it decides the sidebar
 * should collapse into a floating toggle.
 *
 * CSS !important beats non-!important inline styles per the cascade,
 * so these rules are bulletproof against the JS.
