   Product filters — search results and category archives

   Two states. Without JavaScript the panel is an ordinary form sitting above
   the grid. With it — signalled by `html.mg-js`, set inline in the head — the
   panel becomes an off-canvas drawer and the button that opens it appears.
   Everything below is written so the plain state is the default and the
   drawer is the addition.

/* ==========================================================================
   Enhanced: the panel becomes a drawer

   Keyed off `html.mg-js`, which header.php sets from an inline script in the
   head — so the panel is already off-canvas on the first paint. Waiting for
   this file's own script to add a class meant the panel rendered inline for a
   frame first, and flashed.

   Nothing here is keyed off JavaScript having *run*, only off it being
   available. With scripting off there is no `mg-js`, so the panel stays the
   plain inline form above the grid and still submits.
