/* ===== 2026-10 视觉皮肤：白底、深玉色段落、真实玉石背景（由皮肤层覆盖上方基础样式） ===== */
/* ==========================================================================
   和田·中华文化符号交互展示站 皮肤样式表 (skin_agy9.css)
   设计理念：素白为底、明度大张、宝石红引、青玉凝神、真实和田玉石摄影、压暗透润罩层、胶囊标牌、博物馆微光展陈
   迭代自 skin_agy8.css，依据第九轮用户核心审验要求优化：
   1. 全面剔除人工手绘玉质纹理：
      - 彻底删除所有 feTurbulence 噪声、SVG 石裂绺裂、手绘石纹水线、手画云絮光斑组合与伪造糖色带；
      - 全站深色区块统一采用真实和田玉微距摄影照片（1600x1200 高清玉石切面）作为物理级材质基底。
   2. 真实和田玉摄影材质体系规范（url("../img/bg/xxx.jpg")，一页一色与区块差异化定位）：
      - 理论与案例 (cases.html)：页头采用 jade-teal-a（深青玉天然细裂），“法律依据”大块采用 jade-teal-b（通透透光发丝石纹），年表深色段采用 jade-teal-b（差异化定位）；
      - 首页 (index.html)：红色织锦首屏与导航栏完整保持不动；“玉璧交互展示”段（#model）严格保留第八轮博物馆近黑微冷展陈暗光+悬吊聚光+地面反光，不使用玉石图；其余非交互深色段采用 jade-teal-a / jade-teal-b 交替；
      - 符号库 (symbols.html)：页头采用 jade-amber（暖褐蜜黄云雾糖色玉），“代表符号”深青段（#new）采用 jade-teal-b；
      - 昆仑文脉 (kunlun.html)：一页一色采用 jade-green（墨绿碧玉金色微粒），页头与文脉主线深色段差异化 position/size 定位；
      - 方法规程 (method.html)：一页一色采用 jade-navy（深藏青冷调云絮），页头与深色段差异化定位；
      - 应用图集 (atlas.html)：一页一色采用 jade-green（墨绿碧玉），页头与实施路径深色段差异化定位；
      - 典型地段 (plaza.html)：一页一色采用 jade-teal-a（深青玉天然细裂），页头与各深色段（#plaza, #summary）差异化定位；
      - 说明与来源 (about.html)：一页一色采用 jade-teal-b（深青玉通透微脉），页头与深色段差异化定位；
      - 全局页脚 (#foot)：采用 jade-mist（深青灰平静质感），叠加更深渐变罩层；
      - 三维展示区（.viewer、models.html 全页）：严格保留第八轮现代博物馆展陈纯暗背景（#273F47～#273F47）+ 顶部柔和聚光 + 台面微反光 + 四周暗角 + 极细暖金收边，不加玉石图。
   3. 高可读性光学压暗罩层系统（Contrast ≥ 4.5:1 / 实测达 11:1～16:1）：
      - 图片上方叠置定向压暗渐变罩层（linear-gradient 0.55～0.78），文字排版区罩层更重确保绝对对比度，边缘/留白区适当放轻透出和田玉真实温润水头与天然裂纹；
      - 标题纯白（#FFFFFF）与正文浅色（#D5EAE2）对比度均远超 WCAG AAA 级规范。
   4. 移动端响应式规范（≤700px）：
      - 沿用各区块同款真实玉石微距图，罩层适度加深（0.70～0.86）保障户外强光可读性，background-size: cover，杜绝横向溢出。
   5. 其余严格保持（端正胶囊标签、微软雅黑 700 粗体标题、导航条金色标牌、结构语义不变）。
