/* .card already sets overflow-x:auto, which per the CSS overflow spec forces its overflow-y to
   auto too — making the card itself (not the page) the sticky-positioning container. That's
   normally invisible since the card's height isn't bounded, so nothing ever scrolls inside it.
   Adding a max-height here is what actually turns it into a scrolling panel, so the `th` sticky
   rule above has something real to stick to — freezing the header while long tables scroll. */
