\caption{Rendering and layout checks with original simulated data. (a) 30,000 normally distributed points (seed 2026), painted in input order at 300 dpi with marker fill opacity 0.3; axes remain vector. (b) A damped sinusoid with a supplied interval of fixed half-width 0.15, not a fitted confidence interval. (c) Two outlined blocks and italic text with a halo, composited together at 60 percent opacity. Thick strokes and the text halo extend beyond their layout envelopes. (d) Fixed-size blocks with unequal heights in a nested grid, including automatically reserved panel-letter space. No text or stroke is scaled to fit. Recipe and figure: MIT, Mark Marosi.}
