+# Soroban Abacus Education Platform - Comprehensive Roadmap
+
+## Vision Statement
+
+**Mission:** Fill the gap in the USA school system by providing a complete, self-directed abacus curriculum that trains students from beginner to mastery using the Japanese kyu/dan ranking system.
+
+**Target Users:**
+- Primary: Elementary school students (ages 6-12)
+- Secondary: Middle school students and adult learners

+2. **Self-Directed:** Simple enough for kids to fire up and start learning independently
+3. **Gamified Progression:** Games reinforce lessons, feel like play but teach skills
+4. **Physical + Virtual:** Support both physical abacus and AbacusReact component
+5. **Mastery-Based:** Students advance through clear skill levels with certification

+## Integrated Learning Experience Design
+
+### The Core Loop (Per Skill/Concept)
+
+```
+1. ASSESS → Placement test determines current level
+2. LEARN → Tutorial teaches new concept
+3. PRACTICE → Guided exercises with immediate feedback
+4. PLAY → Games reinforce the skill in fun context
+5. TEST → Formal assessment for mastery certification
+6. ADVANCE → Unlock next level, update progress
+```
+
+### Example: Teaching "Friends of 5"
+
+**1. Assessment (Placement)**
+- Quick quiz: "Can you add 3 + 4 using the abacus?"
+- Result: Student struggles → Assign Friends of 5 tutorial
+
+**2. Learn (Tutorial)**
+- Interactive tutorial: "Friends of 5"
+- Steps:
+  1. Show that 5 = 1+4, 2+3, 3+2, 4+1
+  2. Demonstrate on abacus: setting 3, adding 2 to make 5
+  3. Explain heaven bead (top) = 5, earth beads (bottom) = 1 each
+  4. Interactive: Student sets 3, adds 2 using heaven bead
+  5. Practice all combinations
+
+**3. Practice (Structured Exercises)**
+- 20 problems: Set number, add its friend
+- Real-time feedback on bead movements
+- Hints available: "Use the heaven bead!"
+- Must achieve 90% accuracy to proceed
+
+**4. Play (Game Reinforcement)**
+- Complement Race: Friends-5 mode
+- Matching Pairs: Match numbers that make 5
+- Makes practice feel like play
+
+**5. Test (Formal Assessment)**
+- 30 problems mixing friends-5 with previous skills

+2. **Retake Policy:** How many times can student retake certification test? (Suggest: unlimited, but must wait 24 hours)
+3. **Grading Standards:** Strict adherence to Japanese standards or adjust for USA context?
+4. **Physical Abacus:** Should we require physical abacus for certain levels? (Recommend: optional but encouraged)
+5. **Age Restrictions:** Any minimum age? (Suggest: 6+ with parent/teacher supervision)
+6. **Teacher Accounts:** Free for teachers? (Recommend: yes, free for teachers)
+7. **Pricing Model:** Free tier + premium? School licensing? (TBD)
+8. **Content Licensing:** Will curriculum be open source or proprietary? (Recommend: proprietary but allow teacher customization)
+9. **Accessibility:** WCAG compliance level? (Recommend: AA minimum)
+10. **Data Privacy:** COPPA compliance for users under 13? (Required: yes, must be compliant)
+
+---
+
+## Conclusion
+
+This roadmap provides a clear path from current state (scattered features) to target state (complete educational platform). The phased approach allows incremental delivery while maintaining focus on core learning experience.
+
+**Estimated Timeline:**
+- Phase 1 (10-9 Kyu MVP): 3 months
+- Phase 2 (8-5 Kyu): 5 months
+- Phase 3 (4-1 Kyu): 6 months
+- Phase 4 (Dan levels): 3 months
+- Phase 5 (Ecosystem): Ongoing
+
+**Total to Complete Platform:** ~17 months for core curriculum, then continuous improvement
+
+**Priority:** Start with Phase 1 to prove the concept, get student feedback, and validate the learning loop before building the full system.

+# Panda CSS Dynamic Token Usage
+
+## Problem: Dynamic Color Tokens Not Working
+
+When using Panda CSS, color tokens like `blue.400`, `purple.400`, etc. don't work when used dynamically through variables in the `css()` function.
+
+## Root Cause
+
+Panda CSS's `css()` function requires **static values at build time**. It cannot process dynamic token references like:
+
+```typescript
+// ❌ This doesn't work
+const color = 'blue.400'
+css({ color: color })  // Panda can't resolve this at build time
+```
+
+The `css()` function performs static analysis during the build process to generate CSS classes. It cannot handle runtime-dynamic token paths.
+
+## Solution: Use the `token()` Function
+
+Panda CSS provides a `token()` function specifically for resolving token paths to their actual values at runtime:
+
+```typescript
+import { token } from '../../styled-system/tokens'
+
+// ✅ This works
+const stages = [
+  { level: '10 Kyu', label: 'Beginner', color: 'colors.green.400' },
+  { level: '5 Kyu', label: 'Intermediate', color: 'colors.blue.400' },
+  { level: '1 Kyu', label: 'Advanced', color: 'colors.violet.400' },
+  { level: 'Dan', label: 'Master', color: 'colors.amber.400' },
+] as const
+
+// Use with inline styles, not css()
+<div style={{ color: token(stage.color) }}>
+```
+
+## Important Notes
+
+1. **Use `as const`**: TypeScript needs the array marked as `const` so the token strings are treated as literal types, not generic strings. The `token()` function expects the `Token` literal type.
+
+2. **Use inline styles**: When using `token()`, apply colors via the `style` prop, not through the `css()` function:
+   ```typescript
+   // ✅ Correct
+   <div style={{ color: token(stage.color) }}>
+
+   // ❌ Won't work
+   <div className={css({ color: token(stage.color) })}>
+   ```
+
+3. **Static tokens in css()**: For static usage, you CAN use tokens directly in `css()`:
+   ```typescript
+   // ✅ This works because it's static
+   css({ color: 'blue.400' })
+   ```
+
+## How token() Works
+
+The `token()` function:
+- Takes a token path like `"colors.blue.400"`
+- Looks it up in the generated token registry (`styled-system/tokens/index.mjs`)
+- Returns the actual CSS value (e.g., `"#60a5fa"`)
+- Happens at runtime, not build time
+
+## Token Type Definition
+
+The `Token` type is a union of all valid token paths:
+```typescript
+type Token = "colors.blue.400" | "colors.green.400" | "colors.violet.400" | ...
+```
+
+This is defined in `styled-system/tokens/tokens.d.ts`.
+
+## Reference Implementation
+
+See `src/app/page.tsx` lines 404-434 for a working example of dynamic token usage in the "Your Journey" section.

+# Tutorial System Documentation
+
+## Overview
+
+The tutorial system is a sophisticated interactive learning platform for teaching soroban abacus concepts. It features step-by-step guidance, bead highlighting, pedagogical decomposition, and progress tracking.
+
+## Key Components
+
+### 1. TutorialPlayer (`/src/components/tutorial/TutorialPlayer.tsx`)
+The main tutorial playback component that:
+- Displays tutorial steps progressively
+- Highlights specific beads users should interact with
+- Provides real-time feedback and tooltips
+- Shows step-by-step instructions for multi-step operations
+- Tracks user progress through the tutorial
+- Auto-advances to next step on correct completion
+
+**Key Features:**
+- **Bead Highlighting**: Visual indicators showing which beads to manipulate
+- **Step Progress**: Shows current step out of total steps
+- **Error Feedback**: Provides hints when user makes mistakes
+- **Multi-Step Support**: Breaks complex operations into sequential sub-steps
+- **Pedagogical Decomposition**: Explains the "why" behind each operation
+
+### 2. TutorialEditor (`/src/components/tutorial/TutorialEditor.tsx`)
+A full-featured editor for creating and editing tutorials:
+- Visual step editor
+- Bead highlight configuration
+- Multi-step instruction editor
+- Live preview
+- Import/export functionality
+- Access control
+
+**Editor URL:** `/tutorial-editor`
+
+### 3. Tutorial Data Structure (`/src/types/tutorial.ts`)
+
+```typescript
+interface Tutorial {
+  id: string
+  title: string
+  description: string
+  category: string
+  difficulty: 'beginner' | 'intermediate' | 'advanced'
+  estimatedDuration: number // minutes
+  steps: TutorialStep[]
+  tags: string[]
+  author: string
+  version: string
+  createdAt: Date
+  updatedAt: Date
+  isPublished: boolean
+}
+
+interface TutorialStep {
+  id: string
+  title: string
+  problem: string                    // e.g. "2 + 3"
+  description: string                // User-facing explanation
+  startValue: number                 // Initial abacus value
+  targetValue: number                // Goal value
+  expectedAction: 'add' | 'remove' | 'multi-step'
+  actionDescription: string
+
+  // Bead highlighting
+  highlightBeads?: Array<{
+    placeValue: number               // 0=ones, 1=tens, etc.
+    beadType: 'heaven' | 'earth'
+    position?: number                // For earth beads: 0-3
+  }>
+
+  // Progressive step highlighting
+  stepBeadHighlights?: Array<{
+    placeValue: number
+    beadType: 'heaven' | 'earth'
+    position?: number
+    stepIndex: number                // Which instruction step
+    direction: 'up' | 'down' | 'activate' | 'deactivate'
+    order?: number                   // Order within step
+  }>
+
+  totalSteps?: number                // For multi-step operations
+  multiStepInstructions?: string[]   // Sequential instructions
+
+  // Tooltips and guidance
+  tooltip: {
+    content: string                  // Short title
+    explanation: string              // Detailed explanation
+  }
+}
+```
+
+### 4. Tutorial Converter (`/src/utils/tutorialConverter.ts`)
+
+Utility that converts the original `GuidedAdditionTutorial` data into the new tutorial format:
+- `guidedAdditionSteps`: Array of tutorial steps from basic addition to complements
+- `convertGuidedAdditionTutorial()`: Converts to Tutorial object
+- `getTutorialForEditor()`: Main export used in the app
+
+**Current Tutorial Steps:**
+1. Basic Addition (0+1, 1+1, 2+1, 3+1)
+2. Heaven Bead Introduction (0+5, 5+1)
+3. Five Complements (3+4, 2+3 using 5-complement method)
+4. Complex Operations (6+2, 7+4 with carrying)
+
+### 5. Supporting Utilities
+
+**`/src/utils/abacusInstructionGenerator.ts`**
+- Automatically generates step-by-step instructions from start/target values
+- Creates bead highlight data
+- Determines movement directions
+
+**`/src/utils/beadDiff.ts`**
+- Calculates differences between abacus states
+- Generates visual feedback tooltips
+- Explains what changed and why
+
+## Usage Examples
+
+### Basic Usage in a Page
+
+```typescript
+import { TutorialPlayer } from '@/components/tutorial/TutorialPlayer'
+import { getTutorialForEditor } from '@/utils/tutorialConverter'
+
+export function MyPage() {
+  return (
+    <TutorialPlayer
+      tutorial={getTutorialForEditor()}
+      isDebugMode={false}
+      showDebugPanel={false}
+    />
+  )
+}
+```
+
+### Using a Subset of Steps
+
+```typescript
+import { getTutorialForEditor } from '@/utils/tutorialConverter'
+
+const fullTutorial = getTutorialForEditor()
+
+// Extract specific steps (e.g., just "Friends of 5")
+const friendsOf5Tutorial = {
+  ...fullTutorial,
+  id: 'friends-of-5-demo',
+  title: 'Friends of 5',
+  steps: fullTutorial.steps.filter(step =>
+    step.id === 'complement-2' // The 2+3=5 step
+  )
+}
+
+return <TutorialPlayer tutorial={friendsOf5Tutorial} />
+```
+
+### Creating a Custom Tutorial
+
+```typescript
+const customTutorial: Tutorial = {
+  id: 'my-tutorial',
+  title: 'My Custom Tutorial',
+  description: 'Learning something new',
+  category: 'Custom',
+  difficulty: 'beginner',
+  estimatedDuration: 5,
+  steps: [
+    {
+      id: 'step-1',
+      title: 'Add 2',
+      problem: '0 + 2',
+      description: 'Move two earth beads up',
+      startValue: 0,
+      targetValue: 2,
+      expectedAction: 'add',
+      actionDescription: 'Add two earth beads',
+      highlightBeads: [
+        { placeValue: 0, beadType: 'earth', position: 0 },
+        { placeValue: 0, beadType: 'earth', position: 1 }
+      ],
+      tooltip: {
+        content: 'Adding 2',
+        explanation: 'Push two earth beads up to represent 2'
+      }
+    }
+  ],
+  tags: ['custom'],
+  author: 'Me',
+  version: '1.0.0',
+  createdAt: new Date(),
+  updatedAt: new Date(),
+  isPublished: true
+}
+```
+
+## Current Implementation Locations
+
+**Live Tutorials:**
+- `/guide` - Second tab "Arithmetic Operations" contains the full guided addition tutorial
+
+**Editor:**
+- `/tutorial-editor` - Full tutorial editing interface
+
+**Storybook:**
+- Multiple tutorial stories in `/src/components/tutorial/*.stories.tsx`
+
+## Key Design Principles
+
+1. **Progressive Disclosure**: Users see one step at a time
+2. **Immediate Feedback**: Real-time validation and hints
+3. **Visual Guidance**: Bead highlighting shows exactly what to do
+4. **Pedagogical Decomposition**: Multi-step operations broken into atomic actions
+5. **Auto-Advancement**: Successful completion automatically moves to next step
+6. **Error Recovery**: Helpful hints when user makes mistakes
+
+## Notes
+
+- The tutorial system uses the existing `AbacusReact` component
+- Tutorials can be created/edited through the TutorialEditor
+- Tutorial data can be exported/imported as JSON
+- The system supports both single-step and multi-step operations
+- Bead highlighting uses place value indexing (0=ones, 1=tens, etc.)
