<!--
  deck_index.html — 多文件 slide deck 拼接器 · 双概览模式

  概览（默认进入，两种模式按 getSeconds()%5 随机：20% 画廊 / 80% 网格）：
   · grid  自适应网格墙：列数随页数+视口自适应，行多则倾斜变平，scale-to-fit 居中铺满（任意页数都不溢出/不失真）
   · gallery 无限画廊：固定卡片大小，无缝无限平铺 + 缓慢漂移 + 轻微呼吸；一个 tile 含全部页（洗牌），看完所有页才重复
  演示 present：单页 fit 缩放翻页。ESC / ⊞ 回概览。
  性能：manifest 每项可带 thumb（预渲染缩略图），概览即用 <img> 平铺，避免 N 个 iframe 同时加载。

  用法：复制为 index.html；建 slides/ 放每页独立 HTML；编辑 MANIFEST。
  可选覆盖：window.DECK_OVERVIEW = 'grid' | 'gallery'（不写则随机）；URL ?ov=grid|gallery 临时强制。
  键盘（演示）：← / → / Space / PgUp / PgDown / Home / End / 1-9 / P 打印 / ESC 回概览
