/* Dikarya site shell: global bar, local nav and footer.
 *
 * Shared by the Journal (journal.css, no Tailwind) and the Workbench
 * (base_modern.html, Tailwind), so this is plain CSS with every class
 * prefixed `dk-` to stay clear of both. Dark mode is keyed on BOTH forms the
 * layouts use: `.dark` (Tailwind) and `[data-theme="dark"]` (journal.css);
 * partials/site_theme.html sets both.
 *
 * Gold is reserved for the active switcher segment, the active tab underline
 * and badges. Nothing in the navigation is styled as a gold button.
 *
 * Breakpoints (spec section 7): >=1100px full; 768-1099px icon-only What's
 * New and My Jobs; <768px compact bar, scrolling tabs, accordion footer.
 *
 * This file also owns the site-wide type scale (below the shell rules):
 * Libre Baskerville for page titles and section headings, IBM Plex Sans for
 * everything else. journal.css reads the same --dk-h* variables, and
 * Workbench templates use the .dk-h1/.dk-h2/.dk-h3 classes.
