Add tooling to generate SRI hashes for assets
Subresource integrity allows user agents to verify that a fetched
resource has been delivered without unexpected manipulation[0]. I
put theme assets in a json configuration file and save the hashes
to a TOML file that Hugo loads via its theme data mechanism[1].
