Alpine big wall climbing rope physics photography

2x2 grid, 16:9, do this for 4 different subjects and scenes input = [ climber(s) / wall_context / move_beat / capture_medium / rope_and_gear_law ] 

run big_wall_alpine_rope_truth:
subject_dna        := a climber mid-move — hips pressed to the rock, heel raised on a tiny edge, fingers
                      crimped or jammed in a crack, forearm tendons and veins standing out, chalk on the
                      hands and smeared on the holds, taped knuckles, a bloodied fingertip, real strain in
                      the face
context_dna        := infer granite, limestone, or alpine mixed ground; real rock structure — cracks, flakes,
                      chickenheads, lichen, water streaks — never a smooth blank surface
moment_state       := the committing move + causal_hint (reaching for a hold, placing a cam, weighting a
                      foot that might slip)
capture_dna        := shot from a fixed line above or a drone at the same height, 24–50mm equiv, deep dof,
                      hard high-altitude light, fine grain
focal_anchor       := the hand on the hold or the gear placement — tack-sharp; the void below dissolves
light_logic        := hard high-altitude sun with an extreme dynamic range, deep unfilled shadow in the
                      corners and cracks, warm bounce off sunlit granite, a cool shadow side, thin clear air
imperfection       := the rope swinging out of frame, wind lifting a jacket, a slightly awkward real body
                      position rather than a heroic one, gear racked untidily
depth & frame      := void below — hundreds of metres of air, the ground lost to haze or absent entirely, a
                      partner or portaledge as a tiny speck for scale; vertical 4:5 emphasizing the drop
rope_and_gear_law  := the rope must attach to a real point — tied through the harness belay loop, running
                      down to the last piece when leading or up to an anchor when top-roped; it sags in a
                      catenary curve when slack and goes dead straight and thin when loaded; cams and nuts sit
                      in constrictions that could actually hold them; quickdraws hang under gravity; the
                      harness bears visible weight
mood               := exposed, focused, deeply committed

render: one honest instant where true rope physics and real gear make the image.

forbidden — objects: ropes attached to nothing, missing harness or anchor, invented gear, a blank featureless
                     wall with no holds
forbidden — look:    a rigid straight rope with no weight, rope floating away from the body, relaxed
                     effortless posture on hard terrain, gym-flat lighting on an alpine face, no exposure
                     below, clean unchalked hands
