Archetype Sub-90 Dry-Wipe Invariant (Photosynthesis Inverse-Square Law (I ∝ 1/d^2), Limiting Factors & Capillary Potometers (πr^2h/t)): Potometer 2-step check: (1) Halve capillary diameter to radius r = d/2 before computing V = pi*r²*h; (2) Divide by time in minutes/hours. For lamp distance d1 -> d2, multiply light intensity by (d1 / d2)².
