Ship the 47-exercise library in-app: export, fixtures, tests, docs

render.py --export bundles the 25 new motion rigs and info pages;
figure-fixtures.json regenerated for all 47 (the Swift solver reproduces
every new motion, including negative-y pins and the new prop uses). The
fixture count assertion moves to 47, and the no-bundled-motion test now
uses Treadmill - a permanent COVERAGE.md exclusion - since Bench Press
exists. 48 tests green; watch target builds. Coverage handoff complete -
TODO-coverage.md retired.

+# Face Pull
+
+The cable pull to the face — elbows high and wide, rope to the bridge of
+the nose. Small weight, big shoulders-health payoff.
+
+- **Category:** Main circuit
+- **Type:** Machine-based cable pull (rear delts)
+- **Targets:** Rear delts, mid-back, rotator cuff
+- **Prescription:** 3 × 12–15, light
+
+## Setup
+
+Set a rope attachment at face height (or slightly above). Grip with
+thumbs toward you, step back until the arms are straight, and stand
+tall with a slight stagger if needed.
+
+## Execution
+
+1. Pull the rope straight toward the bridge of your nose.
+2. Elbows travel high and wide; at the end the knuckles point back
+   beside the ears.
+3. Pause, then let the arms straighten slowly forward.
+
+## Cues
+
+- Elbows lead and stay at shoulder height the whole pull.
+- Pull the rope apart as it reaches the face.
+- Ribs down; the trunk doesn't lean back to finish the rep.
+
+## Common Mistakes
+
+- Turning it into a row with elbows dropping to the ribs.
+- Too much weight — the shoulders shrug and the trunk sways.
+- Anchor set too low, dragging the pull toward the chest.
+
+## Progression
+
+Add reps and pause length before weight; the Rear Delt Fly machine
+covers the same muscles with chest support.
