…irect Thumbnail hrefs point at datahub.creodias.eu, which 301-redirects to the identical path on zipper.creodias.eu. Only the final zipper response carries CORS headers; the 301 from datahub does not. Since the browser enforces CORS on every hop of a redirect chain, the maplibre WebGL texture fetch (crossOrigin 'anonymous') was blocked at the redirect before reaching the CORS-* image, breaking thumbnails on GitHub Pages. In prod, thumbForMap now rewrites the datahub host straight to zipper, skipping the redirect entirely. Dev still proxies via /thumb (followRedirects).

- Add LICENSE (MIT) and "license"/"homepage"/"repository" fields in package.json. - Add a License section and a live demo link to the GitHub Pages deployment. - Add CI, demo, license, and stack badges to the README header. - Correct the CORS note: the STAC API sends Access-Control-Allow-Origin: *, so no proxy is needed for data; document the datahub->zipper thumbnail redirect and the host-rewrite fix instead.

Summary
Fixes the CORS error that broke quicklook thumbnails in the deployed GitHub Pages app, plus repo housekeeping.
Thumbnail CORS fix
The STAC API is fine in prod (stac.dataspace.copernicus.eu sends Access-Control-Allow-Origin: *). The real problem was thumbnails: their hrefs point at datahub.creodias.eu, which 301-redirects to the same path on zipper.creodias.eu. Only the
final zipper response carries CORS headers — the redirect does not — and the browser enforces CORS on every redirect hop, so the maplibre WebGL texture fetch (crossOrigin='anonymous') was blocked before reaching the image.
thumbForMap in src/components/MapView.tsx now rewrites the datahub host straight to zipper.creodias.eu in production, skipping the redirect. Dev still proxies via /thumb. Zero infrastructure — just a URL rewrite.
