🏭 Topcoat Booth with Realistic Smoke

💡 Implementation Notes

• Realistic Smoke: Multiple <ellipse> elements with staggered animations
• Gaussian Blur: SVG <feGaussianBlur stdDeviation="8"> creates soft smoke effect
• Size Animation: Smoke expands as it rises (rx/ry increase)
• Opacity Fade: Gradual fade from 0.7 to 0 as smoke dissipates
• Layered Effect: Multiple smoke puffs with different timing create depth
• Status Indicator: Blinking green LED for RUNNING, static gray for IDLE

🔧 C# Integration Example

For Blazor/WPF implementation in ModernIndustrialSkin.RenderStack():

• Check fillLevel > 0 to show/hide smoke animation
• Generate 3-5 smoke ellipses with varying sizes and timings
• Use feGaussianBlur filter with high stdDeviation (6-10)
• Apply opacity gradient in animation for realistic fade
• Position smoke at top of stack: y = stackY + height * 0.1
