/**
 * @title NulifyToken
 * @notice A plain, fully-minted ERC-20 launched by the Nulify factory on
 *         Robinhood Chain. The entire supply is minted once, to the factory, at
 *         construction. There is NO mint function, no owner, no pause, no
 *         blacklist, no upgrade path: once deployed the token can only ever be
 *         transferred. This is the self-contained replacement for the Base-native
 *         "B20 asset" precompile, which does not exist on Robinhood Chain.
 * @dev The factory receives the full supply and splits it into the bonding-curve
 *      slice, the vesting slice, and any owner-instant distribution slice.
