/* =========================================================
   LandS Labs — ITERATION 1 / 2
   Direction: LAND-SURVEY BLUEPRINT (cyanotype ⇄ drafting vellum)
   The "plot of land" rendered as an architect's survey:
   self-drawing contours, registration crop-marks, marching
   measurement lines, a live coordinate readout.
   Display: Instrument Serif · Body: Schibsted Grotesk
   Technical labels: Spline Sans Mono
   Default = drafting vellum (blue ink on cool white)
   Dark    = classic cyanotype (chalk lines on prussian blue)
