Author the machine exercise circuit with props and corrected hip machine motions

Fourteen Planet Fitness machine exercises join the rig library, each with
authored motion, info page, and schematic equipment via the new props layer
(scene shapes, cables, bars, pads) rendered in lockstep by render.py and the
in-app figure renderer. Abductor and Adductor are authored face-on with the
real seated machine motion — knees-bent legs swinging apart/together against
knee pads — replacing the earlier middle-split depiction. The watch target
now bundles the figure renderer and motion rigs too.

+# Shoulder Press
+
+The seated overhead press — vertical pushing strength with the trunk braced
+against the pad.
+
+- **Category:** Main circuit
+- **Type:** Machine-based vertical press
+- **Targets:** Deltoids, triceps, upper trapezius
+
+## Setup
+
+Sit with your back against the pad and grip the handles just outside
+shoulder-width, elbows bent so the handles start at shoulder height. Plant your
+feet flat and set your ribs down over your hips.
+
+## Execution
+
+1. Press the handles straight up until your arms are nearly extended — stop
+   short of locking out the elbows.
+2. Pause at the top without shrugging, then lower under control back to shoulder
+   height.
+3. Keep your neck relaxed and your back flat on the pad the whole rep.
+
+## Cues
+
+- Press up, not forward — the handles travel over the shoulders.
+- Keep the ribs down; don't arch the lower back to help the press.
+- Shoulders stay set — avoid shrugging the handles up with the traps.
+
+## Common Mistakes
+
+- Locking the elbows hard at the top.
+- Shrugging the shoulders to finish the press.
+- Arching the lower back off the pad as the weight gets heavy.
+
+## Progression
+
+Add weight in small increments once all four sets of ten are smooth; move to a
+single-arm press for even loading and extra core demand.
