   PE//1 — PREDICTION ERROR
   Design system for Chi-Wei Lee, NeuroAI.

   THESIS. The cortex does not transmit the signal. It transmits the
   residual between what it predicted and what arrived. This site is
   built on that rule: content is a prediction error being resolved.

   CHROMA IS SEMANTIC — this is enforced, not decorative:
     --pre  (magenta) = top-down prediction, descending
     --sig  (teal)    = bottom-up evidence / error, ascending
     --inh  (violet)  = inhibition, gating, suppression
   Anything that is frame, rule, or label stays achromatic.

   TWO REGISTERS ARE TWO IMAGING MODALITIES, NOT AN INVERSION:
     dark  = 2P IN VIVO   — live two-photon recording.
     light = PAPER DAY    — wet pigment moving across a stained sheet.

   Zero dependencies. Hand-written CSS, Canvas2D and WebGL.
