/* Mrrp Research (/tutkimus/, /en/research/): the research branch's own site.
   Polished old-school lab: the whole viewport framed in candy pink with print registration marks, a nav with the MRRP badge in the middle and a
   jump-to palette under it, giant thin condensed titles, and full-bleed bands that alternate plum night and magenta,
   each with dithered duotone imagery made by script from our own recordings and CC0 photos (logo/mrrp-research/
   source/dither.py; provenance in notes/img-provenance/research/). One reading order, centred: bands carry the
   polish, not columns. Faces: Big Shoulders Display (titles), Instrument Sans (prose), Departure Mono (labels and
   data), Jersey 25 only in the badge and seal. All OFL 1.1, licences in /fonts/LICENCES.md. Only this page loads it. */
