/* ======================================================================================= Refactored-safe OAS Download Button (multi-project aware) - Shows a "Download API spec" button on *endpoint* pages in /reference/ - Builds the OpenAPI file index from: /openapi - Caches parsed index in sessionStorage (6h) unless DISABLE_CACHE is true - Works in Refactored SPA + (optionally) iframe-rendered reference IMPORTANT BEHAVIOR (per your requirement): - We NEVER show customer-facing errors. - If the button already exists, we NEVER remove it just because resolution fails. - If we can resolve a better spec, we update the existing button link in-place. - If we cannot resolve (or index fetch fails), we keep the existing button and stay silent.
