/*!
 * Keystone — Bootstrap 6 corporate site
 *
 * Design language: a firm that has been there a while. Cool stone ground, one
 * deep navy accent, generous rules, and type that stays sober. No gradients.
 *
 * The structural idea carrying the identity is navigation. Corporate sites have
 * four sections with several columns each, and almost every Bootstrap template
 * ships a flat five-item navbar that collapses under a real company's IA. The
 * mega menu here is declared once and rendered twice — as panels on desktop,
 * as nested <details> in the drawer on mobile — so the two cannot diverge.
