Shoulder and pelvis widths grow to human-like proportions per profile (shoulders wider than hips for neutral/male, reversed for female) and are now drawn — bars across the attach points that read near-full-width face-on and as a shoulder/hip nub in profile, so limbs visibly hang from a torso instead of a point. Orbiting no longer re-solves IK pins in the rotated view (pins are canvas targets in the authored camera): the pose resolves first and the posed body rotates, which fixes hands sticking to stale screen points mid-orbit (Cat-Cow, Bird Dog, Plank). Leg Extension and Leg Curl swap their ankle bars for a machine roller disc — a new `roller` prop riding the shin's press side. Fixtures regenerated; both renderers updated in lockstep.

Exercise Library
Reference material for exercises the app knows about — one folder per exercise, named exactly as the exercise appears in the app.
Each entry contains:
info.md— the details, always in this order: a one-line summary, quick facts (Category, Type, Targets, Prescription), then Setup, Execution, Cues, Common Mistakes, and Progression (easier → harder — get strong by making the move harder, not by endless reps).motion.json— the exercise scripted as key frames of joint angles on the shared rig (proportions in the library-levelbody.json), with IK pins for planted hands/feet and tween timings. This is the canonical source for all visuals and for the in-app animation planned for the lower half of the exercise screen.- Generated from it by
render.py(never hand-edited):frames/frame-N.svg(one per key frame),preview.gif(the tweened loop), andvisual.svg(the primary frame, for static contexts).
The rig and the visual language — right limbs dark / left limbs light with an
embedded R/L legend, nose tick for facing, teal on the working parts, timing
that encodes tempo, plus figure profiles, flipping, and theming — are defined
in SYSTEM.md, along with the motion.json schema and rendering
instructions.
The library lives at the repo root, deliberately outside the app targets' source folders, and is not bundled into the app yet — the in-app presentation format is still being worked out.
