geoBoundaries fills shapeISO with the bare country code for some countries (every Spanish region got "ESP", every Chinese "CHN", also Chile/Oman), so marking one region lit up the whole country. build-atlas-geo.mjs now keeps shapeISO only when it is a real "XX-..." subdivision code and otherwise synthesizes a unique per-country id from the region name. Regenerated admin1.geojson.gz: Spain/China/ Chile/Oman now carry distinct region codes (countries with real codes, e.g. Germany, are unchanged).
