AR (Augmented Reality)

Use when the user is building AR on WebXR (immersive-ar) or native (ARKit/ARCore/OpenXR).

Fast Defaults

• Prefer stable world-locked content; avoid screen-locked UI unless necessary
• Use clear permission prompts and visible camera-on indicators
• Start with: hit-test + placement + anchors + simple interaction

AR Capability Checklist

• Plane / mesh detection
• Hit-test (placing content onto surfaces)
• Anchors (persistent placement)
• Occlusion (depth) and lighting estimation if available
• Safety boundaries (keep critical UI in view, avoid distraction)

Debug Checklist

• Confirm session type (WebXR immersive-ar) or native runtime
• Verify tracking origin and world scale (1 unit = 1 meter)
• Confirm anchor lifetimes and relocalization handling
