/* Shared "plegable" (collapsible) widget pattern for the owin6g
   simulations. mobile.js toggles a `mob-active` class on <body>
   whenever the pattern should engage — either because the viewport
   is narrow (<= 720px) or because the page opted in with a
   `mob-always` class on the body. All CSS rules key on
   `body.mob-active`, so a single rule set covers both cases. */
