/*
 * Brands.Ng Marketplace — Premium Frontend (v1.28.0)
 *
 * ARCHITECTURE: design tokens → base/reset → components → responsive
 * layers (mobile-2col mandatory, tablet, desktop, large desktop). No
 * property is declared for the same selector in more than one place
 * per breakpoint tier — this file was rewritten from scratch rather
 * than patched.
 *
 * SCOPING: every rule lives under .bi-mp-page or targets a bi-mp-*
 * class only. No bare element selectors, no generic class names.
 * Self-contained — no external fonts/icons/libraries.
 *
 * Brand: #262578 (navy) / #36D106 (green, CTA only) — Brands.Ng
 * identity, no invented palette.
