/**
 * Calculator shell — styles BOTH the battery payback calculator
 * (design/sections/batterikalkyl.section.json) and the solar calculator
 * (design/sections/solkalkyl.section.json), which reuses these zp-bk__
 * classes because the two are the same object visually.
 * Reuses the calculator language from 83-laddkalk.css; the verdict line is the
 * element that carries meaning here, so it gets the colour — green when the
 * calculation works, muted-warning when it does not.
