## Overview

The SRIR Book site is a static GitHub Pages website whose main workflow is opening the Accelerator Atlas, loading facility GeoJSON, and exploring facilities on an interactive map. The atlas documents marker styling, clustering, facility links, and data/image downloads; the landing page links to the atlas. The README also describes MapLibre and map-style providers. No source excerpts were supplied, so relationships below are limited to those documented in the README; repeated atlas nodes denote distinct capabilities implemented by the same page.

Main entry points: [`facilities-worldwide.html`](https://github.com/srir-book/srir-book.github.io/blob/master/facilities-worldwide.html) (Atlas page), [`index.html`](https://github.com/srir-book/srir-book.github.io/blob/master/index.html) (Landing page), [`data/facilities.geojson`](https://github.com/srir-book/srir-book.github.io/blob/master/data/facilities.geojson) (Storage rings), [`data/free-electron-lasers.geojson`](https://github.com/srir-book/srir-book.github.io/blob/master/data/free-electron-lasers.geojson) (Free-electron lasers)
