fNIRS standstill: frontal near-infrared spectroscopy with synchronous head IMU (single recording)

A single 12-minute standstill recording (2023-12-14) with an Artinis Brite frontal fNIRS headband (24 O2Hb/HHb channels, 75 Hz) and its built-in 6-axis IMU logged on the same clock. The full time-series is provided as an open spreadsheet export (with the channel legend); the proprietary OxySoft raw and project files are included as the authoritative source.

NB: the montage has no short-separation channels, so the fNIRS is dominated by systemic physiology (cardiac ~31%) and is not usable for neural inference without systemic correction (see the accompanying analysis).
