     .outer    — CSS grid driven by shared desktop column tokens
                 (currently 3/5 main, 2/5 sidebar) plus shared max width
     .main-col — left: sections I–VI stacked vertically
     .side-col — right: sticky sidebar (desktop only; hidden ≤1100px)
     Roman numeral .section-num floats LEFT outside .section via
     position:absolute + a tokenized negative left offset.
     This requires .section to have position:relative + a matching
     tokenized left margin.
