/* =========================================================================
   FOUNDATION-v2 — shared, reusable components
   Harvested from the design variants and promoted into the shared system.
   All namespaced; orange (#E88005) stays the only accent.
   Sections:
     A. Header "Hiro Platform" dropdown (.nav-drop) + mobile group (.m-group)
     B. Footer contact block (.foot-contact)
     C. Audience router cards (.router / .rcard) + platform strip (.pchips)
     D. Isometric two-column hero (.iso-hero / .iso-copy / .iso-art)
     E. (removed — Hiro Live dashboard schematic; hero panel carries it now)
     F. Value-prop tile icon (.op-ico — pairs with existing .feat) + current nav
     G. Marketing tiles (.mkt-grid / .mkt)
     H. Hardware line-illustration board (.op-link / .board-fig)
