 * bitmall 黑白模式对比度修复
 * ============================================================
 *
 * 根因：
 *   assets/css/apple-theme.css 第 396-405 行有一个【全局】 body 规则：
 *     body { color: var(--apple-text-primary); background-color: var(--apple-background); }
 *   它在 [data-bs-theme="dark"] 下把整页背景变黑(--apple-background:#000)，
 *   但主题 90% 的核心组件/正文文字来自 main.min.css，是【写死深色】且不引用
 *   --apple-* 变量。于是 dark 模式下，所有透明背景区域（文章正文、侧边栏、
 *   用户中心、各类区块）呈现「黑底 + 深色文字」，对比度崩溃，大量内容看不清。
 *   light 模式下 body 本身可读，但某些次要文字使用了过浅的 --apple-text-* 变量，
 *   对比度也不足。
 *
 * 修复策略：
 *   对【默认主题(非 Apple 风格)】在 dark 模式下做系统性高对比覆盖（深底浅字、
 *   卡片/表单/表格/导航均显式高对比）；light 模式补一条次要文字对比度保险。
 *   使用 html[data-bs-theme=...]:not(.apple-style-enabled) 限定，避免影响 Apple
 *   风格主题自身已用变量实现的暗色表现；全部用 !important 压过 main.min.css 写死色。

 * 英雄遮罩渐变顶部 rgba(0,0,0,.55)、底部 rgba(255,255,255,.25)（浅）。
 * 浅色页下白字/灰字在浅色照片区对比崩溃；深色页下灰字也偏暗。
 * 修复：把遮罩统一加暗（黑白两模式都保证深色底），标题白字+阴影，
 *      meta 提到浅灰白，确保「无论黑白都能看清」。
