Semi-log and Log-log Graph Paper (TikZ, exact print scale)

Printable semi-logarithmic paper with one, two or three log cycles up the page and 5 mm linear cells across, plus a 2 × 3 cycle log-log sheet, all drawn in TikZ at exact millimetre scale on A4 or US Letter. Each decade is labelled 1–9, and finer lines (1–2 by 0.1, 2–5 by 0.2, 5–10 by 0.5) are drawn only while they stay at least 0.78 mm apart, so the sheet remains readable if you raise the number of cycles. Change the paper size, cell size or number of cycles in the settings block at the top of main.tex; an interactive version with up to six cycles is at https://graphpaperpdf.net/semi-log-graph-paper/.
