⚡ Bolt: [performance improvement]

[AstroMyth101]

💡 What: Hoisted invariant time (t) based calculations and state derivations (like pulse attributes) outside of the inner pixel drawing loop (for (let x = 0; x <= width; x += 3)) in both drawScope and drawFlatline functions in src/assets/js/hero-canvas.js.

🎯 Why: In the requestAnimationFrame loop, variables that only depend on time or outer state were being redundantly recalculated for every pixel segment. This is a common architectural bottleneck in canvas rendering that forces the JavaScript engine to evaluate the same mathematical expressions hundreds or thousands of times per frame.

📊 Impact: Substantially reduces the CPU cycles per frame for the canvas animations, making the application more efficient and improving frame stability on lower-end devices without altering the visual output.

🔬 Measurement: Verify the application still builds successfully via pnpm run build and that the animated hero canvases (scope and flatline) continue to display and react correctly to pointer interactions without any visual regressions.
