/* /bess-solutions.html: the UnityESS battery storage range Solentra sells.
   Markup: scripts/bess-page.mjs. Loaded after styles.css, legal.css and

   Two label styles only: the eyebrow (12.5px, 600, .14em) for section-level
   labels, and the products dt style (11.5px, 600, .06em) inside components. */
