 * Layout shell: topbar (56px) + sidebar (240px) + main content.
 *
 * Mục tiêu (so với 3-tier header cũ):
 *  - Sidebar bên trái (giống ShopVia1S/Dashboard)
 *  - Topbar mỏng chỉ chứa logo + search + balance + bell + avatar + lang
 *  - Mobile: sidebar collapse thành drawer + backdrop
 *  - Theme: Shopee red #ee4d2d / #f53d2d / #f63 (KHÔNG dùng AdminLTE)
 *
 * KHÔNG dùng !important rộng rãi — chỉ override khi cần đè CSS legacy.

 * Strategy: bump max-width sao cho content fill ~95% available space

 * readability ở 4K (cards 3-col không quá 900px/card).
 *
 * `.cs-content` là flex item bên trong `.cs-main` (flex column).
 * Cross-axis stretch + max-width → tự động left-anchor khi clamp.
 * Khi `available < max-width` → content = available (fluid full).
 * Khi `available > max-width` → content = max-width (cap).
 *
 * Math (sidebar 240 + padding ~80 = 320px overhead):
 *   < 1920  → cap 1600 (fluid <1920 viewport vì available ≤ 1600)
 *   1920+   → cap 1820 (fluid 1920–2140 viewport)
 *   2400+   → cap 2200 (2K/2.5K — fill ~95% @ 2554)

/* --- Sidebar sections ---
 * Phase D: section headers cần "đậm và rõ hơn" theo feedback user.
 * Trước: 10px / weight 800 / màu text-mute (xám nhạt) — trông như label phụ.
 * Sau: 11.5px / weight 900 / màu --cs-text (gần như đen) + accent line đỏ ngắn
 * bên trái để tạo visual anchor cho mỗi nhóm.
 *
 * Implementation:
 *   - Symmetric vertical padding (12/4) cho phép `::before { top: 50%; translateY(-50%) }`
 *     tự align với center của bounding box mà KHÔNG cần margin-top hack.
