   Styles for the /energy section. Everything here is a *delta* on top of
   the theme's existing vocabulary — the templates reuse `.container`,
   `.btn/.btn-primary`, `.section-badge*`, `.breadcrumb*`, `.catalog-hero*`,
   `.catalog-list*`, `.catalog-seo*`, `.product-category*`,
   `.product-breadcrumb*`, `.product-hero*`, `.product-desc-content*`,
   `.product-specs*` and `.specs-*` wherever they fit.

   Tokens, radii, colours, transitions and breakpoints follow global.css /
   catalog.css / product.css (1439 / 1023 / 767 / 480).

   `.catalog-hero__content` right under the H1. Only the two elements the
   catalog hero has no equivalent for are new — the tagline line and the CTA
   row; the paragraph reuses `.catalog-hero__desc`.

   short, but an energy listing carries a three-level breadcrumb and a
   wide H1, so on narrow screens the text slid under the photo.

   Fixed here, scoped to the modifier, so `catalog.css` and every
