   灯箱「黑色框」修复（2026-10-22）
   现象：手机上点开图片放大时，会出现一块黑色方框盖在图上 / 图周围一圈黑。
   原因有三个，叠在一起：
     ① .kanso-flash-lightbox img 的 box-shadow 是「0 15px 50px 纯黑」，
        在 82% 的黑色遮罩上本来就看不见，却要按 50px 的扩散范围做离屏模糊，
        是黑色块最典型的来源（阴影层被切 tile 后就会露出黑色矩形）。
     ② 图片用 opacity:0 → 1 淡入，而 <img> 一旦进入透明组就要单独建层，
        层重建期间该区域按无内容合成，露出的是黑色遮罩。
     ③ JS 要等 img.decode() 才淡入，等待期间图片层恒为 0，就是一整块黑。
   处理（只对 ≤782px）：去掉阴影；改用 visibility 控制显隐（不产生透明层）；
   取消过渡，配合 JS 里「不等待 decode、就绪即显示」，把黑窗压缩到一帧。
   桌面端保留原有淡入与阴影，观感不变。
   ========================================================================== */

   灯箱遮罩不透明化（2026-10-22 二次修复，依据真机截图）
   真机（ColorOS/Android WebView）截图显示：点开图片的中间帧里，
   82% 半透明黑遮罩只绘制出了上面 1/3，下面直接露出原页面与大图，
   有一帧甚至整层没画出来、页面完全可见——
   这是半透明全屏层的逐瓦片合成撕裂：每一块瓦片都要与页面内容混合，
   瓦片没画完的区域就按「无内容」露出下层。
   处理：手机端遮罩改纯黑不透明。纯色层在合成器里走最快的实心填充路径，
   不做逐像素混合，瓦片未完成时也几乎不可感知；观感上 82%→100% 黑
   在这个深色主题里几乎无差。桌面端维持半透明淡入不变。
