ChromeMask doesn't work here because the site is using client hints:
```js
// 判斷是否有 Client Hints，並額外處理brave瀏覽器
if (navigator.userAgentData && navigator.userAgentData.brands) {
// 【路徑 A】有 Client Hints 的瀏覽器 (Chrome, Edge, Brave...)
try {
var brands = navigator.userAgentData.brands.map(function(b) { return b.brand.toLowerCase(); });
var isBrave = brands.indexOf("brave") > -1;
if (isBrave) {
// 1. 如果是 Brave，明確拒絕
console.warn("Brave browser blocked by Client Hints.");
browserIsAllowed = false;
} else {
// 2. 如果不是 Brave，檢查是否為 Chrome 或 Edge
var platform = navigator.userAgentData.platform.toLowerCase();
var hasAllowedBrand = brands.indexOf("google chrome") > -1 || brands.indexOf("microsoft edge") > -1;
var allowedPlatforms = ["windows", "macos", "android"];
var hasAllowedPlatform = allowedPlatforms.includes(platform);
if (hasAllowedBrand && hasAllowedPlatform && checkCoreFeatures()) {
browserIsAllowed = true;
}
}
} catch (e) {
console.warn("Client Hints check error:", e);
browserIsAllowed = false; // 出錯則不允許
}
} else {
// 【路徑 B】沒有 Client Hints 的瀏覽器 (Safari, Firefox...)
var isEdgePC = ua.indexOf("edg") > -1;
var isChrome = ua.indexOf("chrome") > -1 && !isEdgePC;
var isSafari = ua.indexOf("safari") > -1 && ua.indexOf("version") > -1 && !isChrome && !isEdgePC;
// 主要目標是放行 Safari 和 Edge 的 iOS/Android 版
var isEdgeIos = ua.indexOf("edgios") > -1;
var isEdgeAndroid = ua.indexOf("edga") > -1;
var isChromeIos = ua.indexOf("crios") > -1;

ChromeMask doesn't work here because the site is using client hints to detect Chrome:
```js
// 判斷是否有 Client Hints，並額外處理brave瀏覽器
if (navigator.userAgentData && navigator.userAgentData.brands) {
// 【路徑 A】有 Client Hints 的瀏覽器 (Chrome, Edge, Brave...)
try {
var brands = navigator.userAgentData.brands.map(function(b) { return b.brand.toLowerCase(); });
var isBrave = brands.indexOf("brave") > -1;
if (isBrave) {
// 1. 如果是 Brave，明確拒絕
console.warn("Brave browser blocked by Client Hints.");
browserIsAllowed = false;
