v0.18.1

Added

• AgentBody: standing character (head, torso, arms, legs). Motions still, idle, walk, run, and talk. Optional say for a speech bubble. Same face config as AgentAvatar. Pass it as avatar on welcome surfaces. Exports AgentBody, AGENT_BODY_PARTS, and related types from devnonla-ui.

Changed

• AgentAvatar idle bobs the body, blinks, and glances.
• ChatWelcome default avatar uses motion="idle".
• --nonla-mono-text-size matches --nonla-base-text-size (no longer one pixel smaller).

Fixed

• MermaidBlock uses --nonla-font from .nonla-ui (Inter Variable) in rendered diagrams.

Upgrade notes

• AgentAvatar look no longer accepts "up". Use "up-left" / "up-right", or AgentBody with look="up" for a view from behind.
• To keep mono one pixel under body text, set --nonla-mono-text-size: calc(var(--nonla-base-text-size) - 1px) on .nonla-ui.
