/* Shared Layout - HSUK product family (Everything Cloud, CodeFetch, Code2Api, ...)
   Site chrome only: header, nav, footer, content-box card system.
   Structure only — every color is a var(--color-*) token, defined per-site
   in that site's own local styles.css. See websites/CLAUDE.md.
   Opt-in content patterns (step animations, expand/collapse tabs, etc.)
   live in components.css / components.js instead — not every page uses
   them, so they don't belong in this always-loaded file. */

  /* .three-column-content's desktop height (90%, see base rule) is a
     multi-column-layout trick: constraining the box height lets columns
     fill side-by-side instead of one tall column. At column-count: 1
     that same height constraint instead makes the browser overflow
     content into an *implicit* extra column off to the right — CSS
     columns are a horizontal-overflow mechanism, so height: 90% here
     doesn't just clip, it produces a real second column WebKit lays
     out past the visible viewport. height: auto lets the box grow to
     fit its content instead. (Confirmed via computed-style inspection:
     child elements report the correct 1-column width individually, but
     the last one is still positioned at left: 380 — a second column —
     while the container itself is only 370px wide.)

     WebKit/Safari can also render a phantom extra column purely from
     break-inside: avoid-column on a child of a column-count: 1
     container, independent of the height issue above — reset it here
     too so single-column mobile layout can't be affected by
     column-break hints meant only for the multi-column desktop/tablet
     layout. */
