Stencils. Created to order, for a variety of notebook form factors. Grid columns, squares, dotted, and six (or more) heading sizes. The limiting factor becomes writing small enough to fit actual verbiage on the page. It's not easy to make the notebook page "look like" the website. A COBOL programming text has a section on mocking up the tabular layout. The content has to fit across an exact number of columns, but it's magic to see the spacing work out exactly right. Pre-printed, legal-size (A4) perforated sheets, desktop on one side and responsive views on the back, might be neat. The grids are pre-printed but in faint lines, so we can sketch over the bones.
