/**
 * [INPUT]: 依赖 assets/*-ui.webp 真实截图（prepare-shots.py 产出的像素即坐标系）、index.html 的舞台 DOM、demos.js 写入的 data-step / .on / --p
 * [OUTPUT]: 对外提供暗底舞台、截图自适应、像素坐标叠层（.o）、聚光圈、推镜、注解气泡与四款工具的分步视觉状态
 * [POS]: site/ 的演示视觉层；截图保证界面真实，叠层只做两件事——「仿真 App 状态变化」与「旁白注解」
 * [PROTOCOL]: 变更时更新此头部，然后检查 CLAUDE.md
 *
 * 坐标约定：.shot 声明 --W/--H（截图像素），子元素 .o 用 --x/--y/--w/--h 写截图像素，
 *           字号 --fs 也写截图像素；容器查询单位 cqw 让叠层与截图同比缩放。
