/* EPIC shell — design C for every page (header, mega menu, drawer, page head, prose, archive, footer).
   Tokens + components are the same as design/demos/v7-grade-finder; everything is prefixed .ep- so it never fights Elementor/hello.
   Served as uploads/epic-gradefinder/shell.css (link carries data-no-optimize so LiteSpeed does not strip rules). */
