/* ──────────────────────────────────────────────────────────────────────────
   Fix: WordPress admin footer floating into the middle of tall pages.
   WP core sets html,body{height:100%} and #wpcontent{height:100%}, which caps
   the content box to viewport height. Our tall availability table overflows
   visibly while #wpwrap stays viewport-tall, so the absolutely-positioned
   #wpfooter (bottom:0 of #wpwrap) lands mid-page. Letting the content chain
   grow with its content fixes it. This stylesheet only loads on our own
   plugin admin pages, so these global IDs are safe to override here.
