/**
 * Sprint DS-2.1 — Pixel-perfect visual layer (mobile-first authority).
 *
 * Design authority hierarchy:
 *   1. Mobile reference  — PRIMARY (canonical product language)
 *   2. Tablet reference  — SECONDARY (reflow)
 *   3. Desktop reference — EXTENDED executive workspace (layout expansion only)
 *
 * Desktop must NOT be redesigned independently. It expands the mobile experience.
 * Card radius, glass, glow, typography, and spacing inherit from mobile base rules.
 *
 * Requires: executive-tokens.css, brief-pwa.css, ds-2-identity.css (load this file last).
