  @notice The Typeface contract allows storing and retrieving a "source", such as a base64-encoded file, for all fonts in a typeface.

  Sources may be large and require a high gas fee to store. To reduce gas costs while deploying a contract containing source data, or to avoid surpassing gas limits of the deploy transaction block, only a hash of each source is stored when the contract is deployed. This allows sources to be stored in later transactions, ensuring the hash of the source matches the hash already stored for that font.

  Once the Typeface contract has been deployed, source hashes can't be added or modified.

  Fonts are identified by the Font struct, which includes "style" and "weight" properties.
