💡 Photoredox Catalysis (2D)
Top-down reactor view: photons rain from a lamp bar and excite a photocatalyst that hands electrons to substrate molecules, driving a redox cycle whose turnover you control.
This 2D companion drives the same photoredox cycle as the 3D version — photon absorption, excited-state electron transfer, catalyst turnover — through a flat top-down reactor view instead of an orbitable scene, so the same four controls (light intensity, catalyst loading, substrate reactivity, wavelength) are easier to read against the live turnover, quantum-yield and conversion counters.
Photons fall from a lamp bar into a circular reactor, excite a yellow photocatalyst dot, and a successful electron transfer converts a nearby blue substrate dot to orange — the same rate law as the 3D scene, rendered in plain Canvas 2D.
