   SwiftSums — calculator page layer ("Faceted Focus")

   PHASE 2, STAGE 2. Loaded AFTER ss-tokens.css and never alongside
   tokens.css/app.css. ss-tokens.css supplies the palette, reset, header,
   brand, locale switch, saved menu, save control, proof row and footer;
   this file supplies everything specific to a calculator page.

   Structure this expects:

     .ss-dark                     one navy band, containing:
       .ss-topbar                   the shared header
       .ss-calc-hero                crumbs, title, lead, save
       .ss-calc                     the calculator card, sitting ON the band
     main                         light ground from here down
       .ss-section                  how it works / example / FAQ / related

   Putting the card inside the dark band is the point of the layout: the
   answer lands against navy rather than being one more pale panel on a pale
   page, and the reader has somewhere to look before the prose starts.

   NAMES OWNED BY core.js — do not rename:
     .chip .segmented         built by buildChips()
     .input-shell--invalid    toggled by showError()
     .save-btn                wired by ui.wireSaveButton()
