# Storyboard Extension

**Use when:** Page has multiple sketches (multi-step flows, state changes, transitions)

**Base:** Start with [page-specification.template.md](page-specification.template.md)

---

## What Changes

### 1. Add State Flow Overview (before Page Sections)

After Reference Materials, add:

```markdown
## State Flow Overview

{Brief description of states}

![Overview](Sketches/{page-number}-{page-name}-Overview.jpg)

┌─────────────┐    ┌─────────────┐    ┌─────────────┐
│  STATE 1    │───▶│  STATE 2    │───▶│  STATE 3    │
└─────────────┘    └─────────────┘    └─────────────┘

| State | Name | Visual | Entry | Actions |
|-------|------|--------|-------|---------|
| **1** | {name} | {color/icon} | {trigger} | {actions} |
| **2** | {name} | {color/icon} | {trigger} | {actions} |
```

---

### 2. State 1 = Normal Page Specification

Document State 1 using the standard page spec structure:
- Page Sections
- Objects with OBJECT IDs
- Groups with nested objects

This is the **baseline** that other states reference.

---

### 3. States 2+ = Differences Only

After State 1, add for each additional state:

```markdown
# State 2: {State Name} — Differences from State 1

![State 2](Sketches/{page-number}-{page-name}-2-{state-name}.jpg)

> **The Story:** {User experience narrative}

| Property | Value |
|----------|-------|
| Purpose | {what this state does} |
| Entry | {trigger from previous state} |
| Previous | State 1 |
| Next | State 3 / {options} |

### Changes from State 1

| OBJECT ID | Change | Details |
|-----------|--------|---------|
| `{existing-id}` | Modified | {what changed} |
| `{existing-id}` | Hidden | {why hidden} |
| `{new-id}` | Added | {new element} |

### State 2 Elements

{Only document NEW objects not in State 1}

#### {New Object}

**OBJECT ID:** `{page-name}-{new-object}`

| Property | Value |
|----------|-------|
| Component | [{Component}]({path}) |
| Translation Key | `{key}` |
| SE | "{text}" |
| EN | "{text}" |
```

---

## Key Principles

1. **State 1 is baseline** — fully documented
2. **States 2+ show only changes** — reuse OBJECT IDs
3. **Same IDs across states** — `booking-detail-header` stays the same, just describe what changed
4. **New elements get new IDs** — only in the state they first appear
