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.

+# Incline Bench Press
+
+The barbell press on the tilted bench — same press, aimed at the upper
+chest.
+
+- **Category:** Main circuit
+- **Type:** Free-weight incline press
+- **Targets:** Upper chest, front delts, triceps
+- **Prescription:** 3 × 8–10
+
+## Setup
+
+Set the bench to a moderate incline (around 30–45°). Lie back with the
+bar over the eyes, shoulder blades set, feet planted.
+
+## Execution
+
+1. Lower the bar to the upper chest, just below the collarbones.
+2. Touch lightly, keeping the forearms vertical.
+3. Press straight up to lockout above the shoulders.
+
+## Cues
+
+- The steeper the bench, the more shoulder and less chest.
+- Ribcage up, but hips stay on the pad.
+- Bar path is a straight vertical line on the incline.
+
+## Common Mistakes
+
+- Sliding the bar path out over the belly.
+- Overarching to turn it back into a flat press.
+- Grip too wide for the shorter incline stroke.
+
+## Progression
+
+Work up in weight after the flat Bench Press, not before it; dumbbells
+on the same bench trade load for range.
