/* ============================================================
   ETH Signal — "Obsidian Glass"
   Kính mờ nhiều lớp trên nền đen ánh tím-lam.

   Bảng màu đã chạy dataviz/scripts/validate_palette.js (dark):
     accent #4DE1FF · long #4ADE80 · short #FF5C7A · watch #A78BFA
     → CVD separation PASS · normal-vision floor PASS · contrast PASS
   Hai điểm cố ý:
     • long↔short ΔE 9.3 (deutan) là giới hạn của quy ước trading,
       nên hướng lệnh LUÔN kèm chữ + mũi tên ▲▼, không bao giờ chỉ
       dựa vào màu.
     • Trạng thái "đang theo dõi" dùng TÍM chứ không vàng cam: vàng
       cam vs xanh lá chỉ đạt ΔE 3.3 với người mù màu đỏ-lục (FAIL),
       tím đạt PASS toàn bộ.

   Nguyên tắc kính: lớp phủ trắng mờ + blur ĐẶT TRÊN nền tối đặc, để
   số liệu luôn sắc nét. Chỉ app bar / tab bar / toast mới trong suốt.
