New mechanics: NAUTILUS rosettes — open logarithmic spirals with chambers growing exponentially with radius (replacing closed concentric rings, default for this sketch). Per-field stroke weights (fields.<id>.stroke override). Mid-tone substrates so brightness has headroom in both directions.
Held strong: cubic mesh fills the page (cubicScale ≥ 1.4), schlegel takes much space (schlegelScale ≥ 1.0, often bleeding), 11–14 bright Feynman cross-field links per plate.
