Pixel Avatar (Compatibility Alias)

This legacy skill name is retained for backward compatibility.

Primary skill: avatar-portrait.

When this alias triggers:

• Follow the avatar-portrait workflow.
• Set style requirements to pixel art by default (e.g. retro 16-bit, visible pixel structure).
• Preserve likeness from the reference photo.

If the user asks for a non-pixel style, use avatar-portrait directly and apply their requested style.
