The Design section starts with a Concepts list. Each concept gets one
sentence, under the name the code gives it. Storage calls the
transformed images variants, and the sentences it changed for that are
shorter. Its paths end in the source key and the variant key, and it
lists the image cache's tables in the database. Architecture names
internal/providers and lists the packages that work with the concepts.
No code or test changes.
