/* ═══════════════════════════════════════════════════════════
   Mother Passport — Shared Base Styles / Design System
   v2 (August 2026)

   LOAD ORDER CONTRACT (important):
   This file is always linked BEFORE responsive.css and before any
   page's own <style> block. That means page-specific rules win over
   anything here. So this file is a safe FOUNDATION: it sets global
   defaults and a component library, and never fights a page's own
   layout. Enhancements here only take visible effect where a page
   does NOT already define its own rule.

   Every selector from the original base.css is preserved with the
   same geometry, so the 3 pages that already linked base.css do not
   shift. New components and polish are additive.
