## Features

### Permit (EIP-2612)

Gasless approvals via off-chain signatures:

```solidity
function permit(
    address owner,
    address spender,
    uint256 value,
    uint256 deadline,
    uint8 v, bytes32 r, bytes32 s
) external;
```

### Minting

Only addresses with `MINTER_ROLE` can mint:

```solidity
function mint(address to, uint256 amount) external onlyRole(MINTER_ROLE);
```

### Burning

Any holder can burn their own tokens:

```solidity
function burn(uint256 amount) external;
function burnFrom(address account, uint256 amount) external;
```

### Access Control

Uses OpenZeppelin `AccessControlDefaultAdminRules`:

| Role                 | Description             |
| -------------------- | ----------------------- |
| `DEFAULT_ADMIN_ROLE` | Can grant/revoke roles  |
| `MINTER_ROLE`        | Can mint new CTR tokens |
