Scene shapes, cable anchors, bar angles, pad perpendiculars, and roller offsets all resolve in the authored view exactly as before, then rotate about the world-vertical axis through the root anchor - the same resolve-then-rotate pattern as the figure's pins and the mat - so at the authored yaw every exercise renders bit-identically to today, and under an orbiting camera the equipment turns with the figure while staying welded to its hands and feet. Scene lines gain an optional depth plane (z) and slab extrusion (depth) so seats, backrests, and platforms keep form edge-on; the rect shape is retired (re-authored as slab lines). All 14 machines' props re-authored with depths and verified at eight orbit angles. The fixture snapshots move into the pipeline as render.py --fixtures and now cover orbit-presentation samples with resolved prop primitives for a spread of prop flavors; the in-app renderer resolves props in MotionSolver (lockstep with resolve_props) and the view just draws primitives.

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.
