/* Heat pumps (5a) and Optimize My Heat Pump (5b): the v13 layout (Planning/design-review/Heat-Pumps-v13-Oct30.html,
   agreed Oct 30, 2026) on the H tokens in h.css. Sizes follow v13 so every label and button fits one line at 340px.
   All classes carry an hp- prefix so they don't collide with h.css (.panel, .two, .grp ...). */
