/** |

* Boots Yatra's sitemap and wires it into whatever generates sitemaps on the |
| 15 |
* site. |
| 16 |
* |
| 17 |
* Yatra trips/classifications live in custom tables, so no sitemap generator |
| 18 |
* can discover them on its own. Strategy: |
| 19 |
* |
| 20 |
* 1. Serve ONE consolidated sitemap at /yatra-sitemap.xml and advertise it in |
| 21 |
* robots.txt — the universal baseline that works with any/no SEO plugin. |
| 22 |
* 2. Additionally register that one sitemap with whichever system owns the |
| 23 |
* site's sitemap so it also appears in their index: Yoast, Rank Math or |
| 24 |
* AIOSEO if present, otherwise WordPress core sitemaps. |
| 25 |
* |
| 26 |
* Exactly one third-party integration is wired (they are mutually exclusive in |
| 27 |
* practice — each disables the others' / core sitemaps), so the sitemap is |
| 28 |
* never listed twice within a single index. |
