/* Option popovers (js/option-pop.js): a small card that says what an option on the Brand page will cause.
   One element (#optPop) for the whole page. Floating card: positioned by the script (fixed, below or above the option's row, inside the main
   column, never over the sidebar); it never takes pointer events. Under 600 px it is a bottom sheet (.opt-pop--sheet) with a Close button.
   Always fully opaque: no opacity animation, a solid surface colour. */
