Add integrity="sha384-..." and crossorigin="anonymous" attributes to all external resources loaded from api.mapbox.com and cdn.jsdelivr.net in the default layout. This prevents tampering with third-party scripts and stylesheets served from CDNs (supply-chain attack mitigation). Resources covered: - mapbox-gl.css (v3.17.0-beta.1) - mapbox-gl.js (v3.17.0-beta.1) - swiper-bundle.min.css (@12) - swiper-bundle.min.js (@12)
