Hand preview mode
Controls in-browser exercise previews only. Use “2D illustration” if the 3D model looks wrong or feels slow.
Hand-heavy jobs (education)
Preview modes do not change exercise logic — match your work context in patient profiles for load-shaped education.
Use WebGL when the browser supports it; otherwise a simple 2D illustration.
Tip: add ?handVisual=flat to any URL for a one-off override without saving.
Live preview (Tendon glides)
Open hand — relaxed start.

Preview mode is visual only — open libraries or the recovery marketplace for structured education.
