/* RM Circle — direct on-chain enrollment (contingency tool).
   Talks ONLY to the injected wallet provider (window.ethereum), so it needs no
   external libraries and no network of its own — CSP-safe (connect-src 'self').
   It builds transactions to the RM Circle contract that the USER signs and pays;
   this page has zero custody and zero authority. If msg.value is ever wrong the
   contract simply reverts and the user keeps their POL (minus trivial gas). */
