/**
 * inc/mishnah-header-menu.php renders identical content for desktop and
 * mobile from one data source - this file is the only place the two are
 * allowed to look different, and that difference is deliberate (hover
 * megamenu vs. vertical accordion), not drift.
 *
 * Colors/type ride on the --mishnah-* tokens from mishnah-global.css so this
 * matches the rest of the site instead of inventing a parallel palette.
