rigc-face Audit report.

Author a face on plain Spine data with rigc — a blink, a gaze shift, a breathing portrait, a head turn (from a flat sheet a few degrees off axis or a per-vertex depth map across its turn ceiling) and slider-driven face dials, built from closed-form deform transforms, derived group tracks, per-part parallax and socket alpha clipping. Use when the request is a talking or living portrait, a standing character, an expression, a head turn or a look dial, such as "rig this face", "make the portrait blink and look around" or "turn the head". Not for Live2D file conversion, cutting a face illustration into parts, or VTuber-style real-time face tracking.
