• src/eve-wiki-client.ts:366-414 (helper)

  Core implementation of summary retrieval using MediaWiki extracts API with retry logic and Wayback Machine fallback for archived content.

  async getSummary(title: string): Promise<string> {

            explaintext: true,
            exsectionformat: "plain",
            format: "json",
            prop: "extracts",
            titles: title,
          },
        });
  
        const pages = response.data?.query?.pages;

        }
  
        return page.extract || "No summary available";
      } catch (error) {
        console.error("Primary EVE Wiki summary request failed, trying Wayback Machine fallback:", error);

          const paragraphs = textContent.split('\n\n').filter(p => p.trim().length > 0);
          const summary = paragraphs[0] || textContent.substring(0, 500);
