/* oss.hanzo.ai — the open-source cloud storefront.
   One page: the editorial story (hero · beliefs · makers) above a searchable
   1,030-app launcher. One stylesheet. Theme-aware (light default, dark via the
   OS or an explicit [data-theme] toggle). Responsive 390 → 768 → 1280 → 1680,
   no horizontal body scroll. CSP-strict: no external font, no external CSS, no
   inline script. Reads the same /meta.json + /blueprints/<id>/ the PaaS loader
   consumes — the machine catalog is untouched. */
