2_columns_25_75 — main column
Main content, colPos 0, span 9 → 765px. Same split as 2_columns, but this layout sets order: 2 so the main column renders second — the narrow column comes first in visual order while staying second in the document.
Secondary column (renders first)
colPos 1, span 3 → 255px, order: 1. Note this layout reads colPos 1 where 2_columns reads colPos 2.
