/*
  [CONTRACT]: Each image chapter resolves its full-bleed shade and optional local typography from its own theme-editor settings; the deck remains full-screen only for motion-safe precision-pointer contexts.
  [TYPOGRAPHY]: Optional per-photo CSS variables override title, lead, and CTA sizes by desktop/mobile band; absent values retain the calibrated defaults.
  [INPUT]: 依赖 OEM story markup、主题 viewport 与 Control Map 组件样式
  [OUTPUT]: 对外提供全屏 deck、章节蒙版、排版、证据栏、Routes 与响应式阅读降级
  [POS]: OEM story 基础视觉层，Control Map 由兄弟样式文件负责，Header 对比状态交由 controller
  [PROTOCOL]: 变更时更新此头部，然后检查 CLAUDE.md
