/*
 * Megamenu panel system — base stylesheet
 *
 * Customise via CSS custom properties in your theme:
 *
 *   --mm-max-width   Max content width inside the panel   (default: 1200px)
 *   --mm-padding-x   Horizontal padding inside the panel  (default: 1.5rem)
 *   --mm-accent      Chevron + link hover colour           (default: currentColor)
 *   --mm-text        Link text colour                      (default: inherit)
 *   --mm-bg          Panel background                      (default: #fff)
 *   --mm-bg-mobile   Mobile accordion background           (default: #f9fafb)
 *
 * The promo slot background has no default — set it via:
 *   .megamenu-promo { background-color: var(--color-primary); }
 *
 * Some link-reset rules use .megamenu-panel a selectors to undo common
 * parent-theme nav styles. Add more specific overrides in your theme if needed.
