Typst dense cheat sheet: 2-column letter page, and list markers inside table cells

For an exam cheat-sheet draft in Typst: #set page(paper: "us-letter", margin: 0.35in, columns: 2), 7-7.5pt New Computer Modern, tight par(leading: 0.42em, spacing: 0.55em), list/enum spacing 0.35em, and headings restyled as gray bars via a show heading block. That fits about 10 compact sections plus 4 tables on one side. Gotcha: table cell content starting with + or - (e.g. [+ need last taken]) is parsed as an enum or list item and renders as '1. need...'. Reword it, or escape it as \+. Also \# gives a literal # in markup. When the course requires handwritten sheets, produce the draft as a copy-from source and leave side 2 blank for the student's own mistakes from a practice exam.
