Tidied up language

A bigger issue needs consideration. Both H2s start with general information and then go into a GOV.UK case study. This format just about works under Building prototypes, but Ideas can be ugly is less clear. This page should present its information in a step process, yet under the 2nd H2, Ideas can be ugly, we're told how prototyping starts. Perhaps the H2s would be better as Product discovery and Running code.
