## Quick Reference (Core Patterns)

### Colors
```python
BG = "#1c1c1c"           # Background (MUST use)
BLUE = "#3b82f6"         # Primary, nodes
YELLOW = "#fbbf24"       # Highlights, emphasis
GREEN = "#22c55e"        # Success, done, positive
RED = "#ef4444"          # Error, negative
GRAY = "#9ca3af"         # Inactive, labels
```

### Scene Template
```python
from manim import *

class MyScene(Scene):
    def construct(self):
        self.camera.background_color = "#1c1c1c"
        # Your code here
        self.wait(2)  # End padding
```

### Audio-Synced Scene (StrictSync)
```python
TIMING = {
    "01": {"start": 0, "end": 5.5},
    "02": {"start": 5.5, "end": 10.0},
}

class SyncedScene(Scene):
    def construct(self):
        self.camera.background_color = "#1c1c1c"
        for seg_id in sorted(TIMING.keys()):
            method = getattr(self, f"seg_{seg_id}", None)
            if method:
                self._run(seg_id, method)
        self.wait(2)

    def _run(self, seg_id, method):
        t = TIMING[seg_id]
        target = t["end"] - t["start"]
        start = self.renderer.time
        method()
        elapsed = self.renderer.time - start
        if elapsed = 1.5
- Place edge labels perpendicular to edge

### MUST NOT
- Use pure black (#000000) background
- Animate elements one-by-one with separate play() calls
- Place nodes too close (< 1.5 units apart)
- Show formulas before building intuition
- End play() without wait()
