      a:()=>`There are two tiers. <strong>Premium</strong> is what our whole team builds at (${pol()} POL entry) — full payments. <strong>Standard</strong> costs about half and pays/earns half at every level. So if a payment ever comes in smaller than expected, it usually came from a Standard-tier position below you. Your tier is <strong>set when you join and can't be changed later</strong> (upgrading advances your level, not your tier), so always join <strong>Premium</strong> and make sure the people you bring on do too.

Upgrade as quickly as practical — ideally using earned POL — because the first two payments at each level are designed to help fund your next upgrade.
