Provisional standfirst. A piece from the How It Works rubric that will later explain steps and for now only shows their shape.
Provisional text. Explanatory pieces have shorter paragraphs and more subheadings than observations. This paragraph is deliberately brief.
First step
Provisional text. Three sentences that would describe a step. No content, only the length of a typical step.
Second step
Provisional text. Three sentences again. The transition from heading to paragraph is checked here for spacing and weight.
What remains open
Provisional ending. A paragraph that says plainly what is not yet clear. This rubric depends on that.
