/* =============================================================================
   MondialPay — Responsive 2027 Foundation Layer
   ---------------------------------------------------------------------------
   Loaded after all core stylesheets. Provides:
     1) Fluid typography via clamp() (no more fixed px fonts that break on mobile)
     2) Consistent spacing + container scale
     3) SVG normalization (no overflow, intrinsic sizing)
     4) Image & media containment (CLS-safe)
     5) Touch-target + safe-area rules for iOS/Android notches
     6) Container-query helpers for truly modular sections
     7) Motion-reduce + contrast-preference respects
     8) Print hygiene
   Target: single source of truth for 2027 best practices.
