/* =========================================================
   MERCEDES-BENZ STUDIO — DELHI NCR
   Common design system, shared by every page (index.html,
   amggtxx.html, merchandise.html, cafe.html): fonts, colour
   variables, the base reset, the background pattern, the
   shared header (logo/nav/sign-in chip/cart icon/mobile menu),
   generic screen/button/tab/eyebrow primitives, the overlay
   backdrop, the sign-in modal + toast, and the header-related
   responsive rules.

   A page that needs to look different from this baseline (for
   example amggtxx.html's outlined uppercase buttons, or its
   inverted dot pattern) simply redeclares that one rule in its
   own <style> block, which is loaded after this file and wins
   the cascade — no need to touch this file for a one-page
   exception.

   Does NOT own: anything page-specific — hero sections, product
   grids, cart drawers, checkout/payment, the Studio journey,
   etc. Those stay in each page's own <style> block.
