# evOo Character Motion — Brand Soul & Motion God

Product priority: **Proaktivität first** (Oos work or clearly wait on you). Motion and SFX serve that — never decorative idle.

Cross-ref: geometry lock in [`CHARACTER.md`](./CHARACTER.md), voice encounter in [`../../VOICE.md`](../../VOICE.md).

## Expressor hierarchy

| Layer | Role | Share of read |
|-------|------|----------------|
| **Eyes** | Asymmetric Kulleraugen lead every beat | ~lead |
| **Mouth** | Primary expressor | ~80% |
| **Hands** | Punctuation only — then rest | ~20% spikes |

Never symmetrize eyes. Never let floating hands steal focus from face.

## Pose thesis (character only)

| Rule | Value |
|------|--------|
| Eyes before mouth | **40–80 ms** lead on pose change |
| Pose transition | **220–320 ms** |
| Spring | Cute / soft / snap — `cubic-bezier(0.34, 1.25, 0.64, 1)` |
| Scope | Character SVG + mascot only — not app chrome |

Tokens: `evoo-character/motion-tokens.ts` (`EVOO_MOUTH_LAG_MS`, `EVOO_POSE_TRANSITION_MS`, `EVOO_CHARACTER_SPRING`).

## SFX & vocals (Web Audio)

Toggle: Settings → Voice → Sound feedback. No vendor branding in UI.

| Cue | Spec |
|-----|------|
| **eOo cold-open** | ≤450 ms, **max 1×/session** |
| **App start** | 180–320 ms mint→violet shimmer (before optional eOo mark) |
| **Interact** | 40–80 ms soft tick |
| **Success** | Mint→gold resolve **or** soft `hm!` vocal — not both loud |
| **Need-you** | Short `ouh?!` + UI chip together |
| **Reactions** | `mhMhh` / `aaah` / `ouh?!` / `mm` — state-change only |
| **Cooldown** | ≥8–12 s between reaction vocals |
| **Level** | **−18…−12 LUFS** perceived (procedural peaks via shared bus gain) |
| **Duck** | Under TTS playback and PTT/listening wash |

Implementation: `apps/web/src/lib/oo-sound.ts`, `oo-vocals.ts`, `oo-voice-mark.ts`, `oo-audio-bus.ts`.

### Nod

| Phase | Vocal |
|-------|--------|
| Down | `mh` (short, low) |
| Up | `Mhh` (slightly longer, rising) |

### Dual-Mind bloom

Reaction vocals may ride the voice-stage cyan/violet bloom — stay **under** the PTT/TTS wash; duck, never compete.

---

## Reduced motion

When `prefers-reduced-motion: reduce`:

- **No vocal loops** and no reaction stems
- **Visual state only** — pose snaps without stagger; no mouth-speak pulse
- Procedural UI ticks may still be omitted (same gate as SFX)

---

## Proactivity (Priority S)

Motion never replaces working/waiting signals. Roster doing-verbs, Heute buckets, and need-you pings are authoritative; face/audio **amplify** them.

See `apps/web/src/lib/agent-activity.ts` and Heute Brief buckets.
