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.
