🧠 Memory Palace in 3D — Forgetting Curve & Spaced Repetition Simulator

The 2D original at this id was an unbuilt placeholder page ("simulation coming later"), so this 3D companion implements the real mechanic its title and description promise: Hermann Ebbinghaus's forgetting curve, R(t) = e^(−t/S), where R is the probability of recall, t is days since last review and S is memory strength in days. Each of the loci around the 3D corridor tracks its own t and S; reviewing an item (by clicking its glowing pedestal) resets t to zero and multiplies S by a technique-dependent boost — modelling how mnemonic encoding and spaced review measurably slow forgetting compared to rote repetition, the same relationship studied in spaced-repetition research (e.g. the SM-2 algorithm's easiness factor).
