/* Direction A · Calibration (approved 2026-10-27).
   The course's core gap is "felt sure vs. was right", so the site reads as a calibration instrument:
   fog paper, graphite ink, signal cobalt, amber for the confidence gap.
   Units ride a sequential cobalt ramp (--u0 … --u7) because units are a sequence. */
