Abstract
M04 formalizes visual ergonomics as measures a page can be scored on. It sets out 1,200 quantitative questions about interface design, measures TPSI, whitespace ratio and two-dimensional saliency heatmaps, and states 4 pt and 8 pt harmonic padding and anti-AI-slop design rules. Its measures are calibrated against three reference sites: paco.me, rauno.me and read.cv [1, 2, 3].
The question set
The monograph scores an interface with 1,200 quantitative questions. Each question is answered with a measurement taken from the page itself.
Harmonic padding
Padding and gaps follow 4 pt and 8 pt steps, so spacing keeps one rhythm across the page.
Whitespace ratio
The whitespace ratio compares the open ground of a layout with its whole area, which turns a sense of room into a number.

Saliency heatmaps
A two-dimensional saliency heatmap maps where attention lands on a page, so the headline and the main action can be checked against where the eye goes.
Calibration
M04 calibrates its measures against three reference sites: paco.me [1], rauno.me [2] and read.cv [3].
Verification
Like every monograph at baltor.ai/showcase/papers [4], M04 pairs its claims with an executable verification suite, held-out counterfactual perturbation checks and known-wrong refusal controls.
