Add 3D loose-leaf chronicle of human civilisation

A Three.js site presenting 20 world history milestones as double-sided loose-leaf pages, with three views: a leather binder with page-flip animation, a golden timeline, and a dotted globe with great-circle arcs. All textures (paper, leather, registration cards, and 18 hand-drawn sketches) are generated procedurally via Canvas 2D, so no external image assets are needed beyond the Earth map. Includes dev helper scripts for screenshots, ASCII previews, and headless verification.
