* allocation are the only limits on a large buy. `deployer` is carried here

* privileges over the token.
* `ERC20Burnable` lets any holder voluntarily burn their own balance; the
* protocol's buyback mechanism does not use it, bought-back tokens are
* locked into `PonsV2BuybackVault` for a five-year vest instead of being
* burned.
