/* Calculator section styling. Shared by tenant sites and the builder preview,
   so a generated calculator looks the same in the panel as on the live page.

   Two layouts, both taken from the mock-ups in sources/tpl:
     .kfc--split  formularz w kartach kroków + sticky karta wyniku z ciemnym
                  nagłówkiem kwoty (makieta „Layout A · split")
     .kfc--sheet  wąska kolumna konfiguracji, pasek ilości i szeroka tabela
                  zestawienia z podsumowaniem (makieta „Layout C · arkusz")
   .kfc--stacked i .kfc--compact to wąskie warianty układu split.

   Colour variables are resolved per template: lead-gen/business-card expose
   --accent/--surface/--line/--muted, the equipment (WYSUW) skin exposes
   --c-primary/--c-surface/--c-line/--c-body. Both are tried before the
   neutral fallback, so the block inherits the tenant's palette everywhere. */
