Add a USDT0 (LayerZero OFT) page to the tokens section - #2795
Conversation
New page docs/tokens/usdt0-layerzero.mdx, placed right after the CCTP page in the sidebar. Covers what USDT0 is, mainnet addresses, how LayerZero fits, integration pointers to the official USDT0 docs, amount precision, constraints to check before listing, and a read-only RPC pre-listing check. Registers the route in routes.txt and llms.txt.

- Adds navbar, route, and LLM index entries.

- #2793 also requires a read-only pre-listing check using Stellar RPC. The generic integration links and fee quote do not provide that check, so the page does not yet let a protocol verify the expected issuer/SAC/OFT configuration before listing USDT0. Add the requested non-mutating RPC example.
- **Bridging in or out.** End users move USDT0 with the [transfer UI](https://usdt0.to/transfer). Programmatic sends from Stellar go through the OFT contract's `quote_send` and `send` functions, with fees paid in XLM. The [USDT0 developer guide](https://docs.usdt0.to/technical-documentation/developer) documents the OFT interface and the message flow. Query `quote_send` for the current fee rather than relying on a documented number.

This is intentional. The page is a short link-out page, like the CCTP page next to it. Issuer flags, home_domain checks, and the pre-listing script are out of scope. Protocols read those values from the network. I updated #2793 to match this scope.

Note for reviewers: the PR preview can lag behind the branch. Yesterday it served only the first build of a series of pushes (commit ad6d114, 18:22Z). Jenkins reported success for the three later commits, but their content never appeared, and a hard reload did not help. A single push today (ed7cb62) deployed fine, so this seems to affect back-to-back pushes only. If the preview looks stale, compare the |

the subject of the sentence gets a little mixed up. might be good to clarify which account it'll land in.

this may not be necessary, really. but it feels a little more "complete" to me?
