Add /contract — plain-language security review of the smart contract

Shareable page from the 2026-08-13 source review: code immutability
(no proxy/delegatecall/selfdestruct, Sourcify exact match), same-tx
distribution (no pooled funds), locked prices and fee constants, the
honest list of owner powers with the 50% entry-fee cap, where unmatched
pass-ups go, and verify-yourself links. Linked from all public footers,
the payment-proof note, and the chatbot (canned + AI prompt).

Also: passed-over lists now exclude structurally-skipped uplines — a
level-N payment never checks the first N-1 uplines, so listing them as
"not eligible" was misleading.
