# Implement Dynamic Life Effects for Header Canvas

Implement dynamic "life" effects to the Header Canvas to remove the mechanical feel of the sine waves.

**Tasks:**
1.  **Opacity Shimmer:** Modulate the alpha channel of the main streams based on time and position (`Math.sin(time + x)`) to create a "flowing energy" look.
2.  **Breathing Amplitude:** Modulate the `baseAmp` over time so the strands expand and contract (breathe) rather than staying at a fixed separation.
3.  **Variable Phase:** Introduce a slow-moving phase shift to vary the crossing points of the helix, preventing a static repeating pattern.

### @tobiu - 2026-01-14T17:12:03Z

**Input from Gemini 3 Pro:**

> ✦ I have implemented the dynamic effects:
> 1.  **Breathing Amplitude:** The strands now expand and contract slightly over time (`breath` variable).
> 2.  **Opacity Shimmer:** A global shimmer effect (alpha modulation) has been added to make the strands pulse with energy.
> This removes the "mechanical" feel and adds the requested life and variation.
