/** |

* Links Yatra's consolidated sitemap into All in One SEO's sitemap index via |
| 12 |
* the `aioseo_sitemap_indexes` filter — a simple URL pointer (loc/lastmod/ |
| 13 |
* count), which is lower-risk than AIOSEO's page-object `additional_pages` |
| 14 |
* filter. AIOSEO then lists /yatra-sitemap.xml as a sub-sitemap in its index. |
| 15 |
* |
| 16 |
* Note: AIOSEO must have XML sitemaps enabled. Even if this index injection is |
| 17 |
* unavailable on a given AIOSEO version, the robots.txt advertisement still |
| 18 |
* exposes /yatra-sitemap.xml, so discovery is never lost. |
