+# 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.
