A morphogen is released from a fixed source at one pole of the tissue and diffuses outward across a real finite-difference concentration field (with decay), forming a smooth spatial gradient — not a self-patterning reaction like Gray–Scott. Every dividing cell reads the local concentration at its position and picks one of three fates by threshold, a French-flag-model positional-information rule.
