The `.ev-sidebar-collapsed .VPSidebar { display: none }` rule was not
wrapped in a media query, causing it to hide the sidebar at all viewport
widths. When a user collapsed the sidebar on desktop, the state persisted
in localStorage; resizing below 960px then caused VitePress's native
hamburger menu to open an immediately-hidden sidebar. Wrapping the rule
in `@media (min-width: 960px)` limits the override to desktop only.
