+# Puck Site Builder - Design Document
+
+## Overview
+
+This document describes the architecture, data model, migration strategy, and security decisions for the SmoothSchedule Puck-based site builder.
+
+## Goals
+
+1. **Production-quality site builder** - Enable tenants to build unique pages using nested layout primitives, theme tokens, and booking-native blocks
+2. **Backward compatibility** - Existing pages must continue to render
+3. **Multi-tenant safety** - Full tenant isolation for all page data
+4. **Security** - No arbitrary script injection; sanitized embeds only
+5. **Feature gating** - Hide/disable blocks based on plan without breaking existing content
+
+## Data Model
+
+### Current Schema (Existing)
+
+```
+Site
+├── tenant (OneToOne → Tenant)
+├── primary_domain
+├── is_enabled
+├── template_key
+└── pages[] (Page)
+
+Page
+├── site (FK → Site)
+├── slug
+├── path
+├── title
+├── is_home
+├── is_published
+├── order
+├── puck_data (JSONField - Puck Data payload)
+└── version (int - for migrations)
+```
+
+### New Schema Additions
+
+#### SiteConfig (New Model)
+
+Stores global theme tokens and chrome settings. One per Site, not duplicated per page.
+
+```python
+class SiteConfig(models.Model):
+    site = models.OneToOneField(Site, on_delete=models.CASCADE, related_name='config')
+
+    # Theme Tokens
+    theme = models.JSONField(default=dict)
+    # Structure:
+    # {
+    #     "colors": {
+    #         "primary": "#3b82f6",
+    #         "secondary": "#64748b",
+    #         "accent": "#f59e0b",
+    #         "background": "#ffffff",
+    #         "surface": "#f8fafc",
+    #         "text": "#1e293b",
+    #         "textMuted": "#64748b"
+    #     },
+    #     "typography": {
+    #         "fontFamily": "Inter, system-ui, sans-serif",
+    #         "headingFontFamily": null,  # null = use fontFamily
+    #         "baseFontSize": "16px",
+    #         "scale": 1.25  # type scale ratio
+    #     },
+    #     "buttons": {
+    #         "borderRadius": "8px",
+    #         "primaryStyle": "solid",  # solid | outline | ghost
+    #         "secondaryStyle": "outline"
+    #     },
+    #     "sections": {
+    #         "containerMaxWidth": "1280px",
+    #         "defaultPaddingY": "80px"
+    #     }
+    # }
+
+    # Global Chrome
+    header = models.JSONField(default=dict)
+    # Structure:
+    # {
+    #     "enabled": true,
+    #     "logo": { "src": "", "alt": "", "width": 120 },
+    #     "navigation": [
+    #         { "label": "Home", "href": "/" },
+    #         { "label": "Services", "href": "/services" },
+    #         { "label": "Book Now", "href": "/book", "style": "button" }
+    #     ],
+    #     "sticky": true,
+    #     "style": "default"  # default | transparent | minimal
+    # }
+
+    footer = models.JSONField(default=dict)
+    # Structure:
+    # {
+    #     "enabled": true,
+    #     "columns": [
+    #         {
+    #             "title": "Company",
+    #             "links": [{ "label": "About", "href": "/about" }]
+    #         }
+    #     ],
+    #     "copyright": "© 2024 {business_name}. All rights reserved.",
+    #     "socialLinks": [
+    #         { "platform": "facebook", "url": "" },
+    #         { "platform": "instagram", "url": "" }
+    #     ]
+    # }
+
+    version = models.PositiveIntegerField(default=1)
+    created_at = models.DateTimeField(auto_now_add=True)
+    updated_at = models.DateTimeField(auto_now=True)
+```
+
+#### Page Model Enhancements
+
+Add SEO and navigation fields to existing Page model:
+
+```python
+# Add to existing Page model:
+meta_title = models.CharField(max_length=255, blank=True)
+meta_description = models.TextField(blank=True)
+og_image = models.URLField(blank=True)
+canonical_url = models.URLField(blank=True)
+noindex = models.BooleanField(default=False)
+include_in_nav = models.BooleanField(default=True)
+hide_chrome = models.BooleanField(default=False)  # Landing page mode
+```
+
+### Puck Data Schema
+
+The `puck_data` JSONField stores the Puck editor payload:
+
+```json
+{
+    "content": [
+        {
+            "type": "Section",
+            "props": {
+                "id": "section-abc123",
+                "background": { "type": "color", "value": "#f8fafc" },
+                "padding": "large",
+                "containerWidth": "default",
+                "anchorId": "hero"
+            }
+        }
+    ],
+    "root": {},
+    "zones": {
+        "section-abc123:content": [
+            {
+                "type": "Heading",
+                "props": { "text": "Welcome", "level": "h1" }
+            }
+        ]
+    }
+}
+```
+
+### Version Strategy
+
+- `Page.version` tracks payload schema version
+- `SiteConfig.version` tracks theme/chrome schema version
+- Migrations are handled on read (lazy migration)
+- On save, always write latest version

+## Component Library
+
+### Categories
+
+1. **Layout** - Section, Columns, Card, Spacer, Divider
+2. **Content** - Heading, RichText, Image, Button, IconList, Testimonial, FAQ
+3. **Booking** - BookingWidget, ServiceCatalog
+4. **Contact** - ContactForm, BusinessHours, Map
+
+### Component Specification
+
+#### Section (Layout)
+
+The fundamental building block for page sections.
+
+```typescript
+{
+    type: "Section",
+    label: "Section",
+    fields: {
+        background: {
+            type: "custom",  // Color picker, image upload, or gradient
+            options: ["none", "color", "image", "gradient"]
+        },
+        overlay: {
+            type: "custom",  // Overlay color + opacity
+        },
+        padding: {
+            type: "select",
+            options: ["none", "small", "medium", "large", "xlarge"]
+        },
+        containerWidth: {
+            type: "select",
+            options: ["narrow", "default", "wide", "full"]
+        },
+        anchorId: { type: "text" },
+        hideOnMobile: { type: "checkbox" },
+        hideOnTablet: { type: "checkbox" },
+        hideOnDesktop: { type: "checkbox" }
+    },
+    render: ({ puck }) => (
+        <section>
+            <div className={containerClass}>
+                <DropZone zone="content" />
+            </div>
+        </section>
+    )
+}
+```
+
+#### Columns (Layout)
+
+Flexible column layout with nested drop zones.
+
+```typescript
+{
+    type: "Columns",
+    fields: {
+        columns: {
+            type: "select",
+            options: ["2", "3", "4", "2-1", "1-2"]  // ratios
+        },
+        gap: {
+            type: "select",
+            options: ["none", "small", "medium", "large"]
+        },
+        verticalAlign: {
+            type: "select",
+            options: ["top", "center", "bottom", "stretch"]
+        },
+        stackOnMobile: { type: "checkbox", default: true }
+    },
+    render: ({ columns, puck }) => (
+        <div className="grid">
+            {Array.from({ length: columnCount }).map((_, i) => (
+                <DropZone zone={`column-${i}`} key={i} />
+            ))}
+        </div>
+    )
+}
+```
+
+#### BookingWidget (Booking)
+
+Embedded booking interface - SmoothSchedule's differentiator.
+
+```typescript
+{
+    type: "BookingWidget",
+    fields: {
+        serviceMode: {
+            type: "select",
+            options: [
+                { label: "All Services", value: "all" },
+                { label: "By Category", value: "category" },
+                { label: "Specific Services", value: "specific" }
+            ]
+        },
+        categoryId: { type: "text" },  // When mode = category
+        serviceIds: { type: "array" },  // When mode = specific
+        showDuration: { type: "checkbox", default: true },
+        showPrice: { type: "checkbox", default: true },
+        showDeposits: { type: "checkbox", default: true },
+        requireLogin: { type: "checkbox", default: false },
+        ctaAfterBooking: { type: "text" }
+    }
+}
+```
+
+## Security Measures
+
+### 1. XSS Prevention
+
+All text content is rendered through React, which auto-escapes HTML by default.
+
+For rich text (RichText component):
+- Store content as structured JSON (Slate/Tiptap document format), not raw HTML
+- Render using a safe renderer that only supports whitelisted elements (p, strong, em, a, ul, ol, li)
+- Never render raw HTML strings directly into the DOM
+- All user-provided content goes through React's safe text rendering
+
+### 2. Embed/Script Injection
+
+No arbitrary embeds allowed. Map component only supports:
+- Google Maps embed URLs (maps.google.com/*)
+- OpenStreetMap iframes
+
+Implementation:
+```typescript
+const ALLOWED_EMBED_DOMAINS = [
+    'www.google.com/maps/embed',
+    'maps.google.com',
+    'www.openstreetmap.org'
+];
+
+function isAllowedEmbed(url: string): boolean {
+    return ALLOWED_EMBED_DOMAINS.some(domain =>
+        url.startsWith(`https://${domain}`)
+    );
+}
+```
+
+### 3. Backend Validation
+
+```python
+# In PageSerializer.validate_puck_data()
+def validate_puck_data(self, value):
+    # 1. Size limit
+    if len(json.dumps(value)) > 5_000_000:  # 5MB limit
+        raise ValidationError("Page data too large")
+
+    # 2. Validate structure
+    if not isinstance(value.get('content'), list):
+        raise ValidationError("Invalid puck_data structure")
+
+    # 3. Scan for disallowed content
+    serialized = json.dumps(value).lower()
+    disallowed = ['<script', 'javascript:', 'onerror=', 'onload=']
+    for pattern in disallowed:
+        if pattern in serialized:
+            raise ValidationError("Disallowed content detected")
+
+    return value
+```
+
+### 4. Tenant Isolation
+
+All queries are automatically tenant-scoped:
+- `get_queryset()` filters by `site__tenant=request.tenant`
+- `perform_create()` assigns site from tenant context
+- No cross-tenant data access possible
+
+## Migration Strategy
+
+### Current State Analysis
+
+The existing implementation already uses Puck with 3 components:
+- Hero
+- TextSection
+- Booking
+
+No "enum-based component list" migration needed - the system is already Puck-native.
+
+### Forward Migration
+
+When adding new component types or changing prop schemas:
+
+1. **Version field** tracks schema version per page
+2. **Lazy migration** on read - transform old format to new
+3. **Save updates version** - always writes latest format
+
+Example migration:
+```typescript
+// v1 → v2: Hero.align was string, now object with breakpoint values
+function migrateHeroV1toV2(props: any): any {
+    if (typeof props.align === 'string') {
+        return {
+            ...props,
+            align: {
+                mobile: 'center',
+                tablet: props.align,
+                desktop: props.align
+            }
+        };
+    }
+    return props;
+}
+```
+
+### Migration Registry
+
+```typescript
+const MIGRATIONS: Record<number, (data: PuckData) => PuckData> = {
+    2: migrateV1toV2,
+    3: migrateV2toV3,
+};
+
+function migratePuckData(data: PuckData, currentVersion: number): PuckData {
+    let migrated = data;
+    for (let v = currentVersion + 1; v <= LATEST_VERSION; v++) {
+        if (MIGRATIONS[v]) {
+            migrated = MIGRATIONS[v](migrated);
+        }
+    }
+    return migrated;
+}
+```
+
+## Feature Gating
+
+### Plan-Based Component Access
+
+Some components are gated by plan features:
+- **ContactForm** - requires `can_use_contact_form` feature
+- **ServiceCatalog** - requires `can_use_service_catalog` feature
+
+### Implementation
+
+1. **Config generation** passes feature flags to frontend:
+```typescript
+function getComponentConfig(features: Features): Config {
+    const components = { ...baseComponents };
+
+    if (!features.can_use_contact_form) {
+        delete components.ContactForm;
+    }
+
+    return { components };
+}
+```
+
+2. **Rendering** always includes all component renderers:
+```typescript
+// Full config for rendering (never gated)
+const renderConfig = { components: allComponents };
+
+// Gated config for editing
+const editorConfig = getComponentConfig(features);
+```
+
+This ensures pages with gated components still render correctly, even if the user can't add new instances.
+
+## Editor UX Enhancements
+
+### Viewport Toggles
+
+Desktop (default), Tablet (768px), Mobile (375px)
+
+### Outline Navigation
+
+Tree view of page structure with:
+- Drag to reorder
+- Click to select
+- Collapse/expand zones
+
+### Categorized Component Palette
+
+- Layout: Section, Columns, Card, Spacer, Divider
+- Content: Heading, RichText, Image, Button, IconList, Testimonial, FAQ
+- Booking: BookingWidget, ServiceCatalog
+- Contact: ContactForm, BusinessHours, Map
+
+### Page Settings Panel
+
+Accessible via page icon in header:
+- Title & slug
+- Meta title & description
+- OG image
+- Canonical URL
+- Index/noindex toggle
+- Include in navigation toggle
+- Hide chrome toggle (landing page mode)
+

+/**
+ * Canonical Feature Catalog
+ *
+ * This file defines the canonical list of features available in the SmoothSchedule
+ * billing system. Features are organized by type (boolean vs integer) and include
+ * human-readable labels and descriptions.
+ *
+ * IMPORTANT: When adding new feature codes, add them here first to maintain a
+ * single source of truth. The FeaturePicker component uses this catalog to
+ * provide autocomplete and validation.
+ *
+ * Feature Types:
+ * - Boolean: On/off capabilities (e.g., sms_enabled, api_access)
+ * - Integer: Limit/quota features (e.g., max_users, max_resources)
+ *
+ * Usage:
+ * ```typescript
+ * import { FEATURE_CATALOG, getFeatureInfo, isCanonicalFeature } from '../billing/featureCatalog';
+ *
+ * // Get info about a feature
+ * const info = getFeatureInfo('max_users');
+ * // { code: 'max_users', name: 'Maximum Users', type: 'integer', ... }
+ *
+ * // Check if a feature is in the canonical catalog
+ * const isCanonical = isCanonicalFeature('custom_feature'); // false
+ * ```
