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.

+# Lateral Raise
+
+The side-delt isolation — raise light dumbbells out to the sides until
+the arms are level with the shoulders.
+
+- **Category:** Main circuit
+- **Type:** Free-weight lateral raise (dumbbells)
+- **Targets:** Side delts
+- **Prescription:** 3 × 12–15, light
+
+## Setup
+
+Stand tall with light dumbbells at your sides, a slight fixed bend in
+the elbows, shoulders relaxed down.
+
+## Execution
+
+1. Raise both arms out to the sides, leading with the elbows.
+2. Stop at shoulder height — arms level, pinkies no higher than thumbs.
+3. Lower slowly back to the sides.
+
+## Cues
+
+- Pour-the-jug: elbows stay just above the hands.
+- Shoulders stay down away from the ears — no shrugging.
+- The weights float up; the trunk never sways.
+
+## Common Mistakes
+
+- Going too heavy and swinging the weights up.
+- Shrugging the traps into the raise.
+- Raising past shoulder height.
+
+## Progression
+
+More reps before more weight; slow negatives and pauses at the top beat
+bigger dumbbells here.
