/* Mobile Beef Plan — single site stylesheet. System fonts only, no external assets.
   Classes for other builders:
     .site-header (+ .brand, nav)  top bar with shared nav; nav a[aria-current="page"] = active
     .site-footer                  footer disclaimer line
     main.container                page body, max-width 1100px; pandoc output styles live here too
     .notice                       amber research-draft banner (pandoc "::: notice" div uses it as-is)
     .placeholder-badge            small amber inline tag: placeholder assumption
     .sourced-badge                small green inline tag: sourced assumption
     .grid-2                       two columns, stacks below 760px
     .card                         bordered panel
     .table-wrap                   wrapper that scrolls a wide table horizontally
     table                         striped rows, olive header (applies to every table)
     label / input / select        label above control; .field = one label+control group
     .kpi (+ .kpi-value, .kpi-label)  big number with caption; .kpi.negative turns value red
     .muted                        secondary grey text
     button, button.secondary      olive primary / outline secondary
     .checklist (ul) > li          checkbox rows; li.done strikes through
     @media print                  hides nav/buttons, un-scrolls tables
