Preparing to fetch BOM details.

Here’s the current BOM for the design (project components only; excludes utility symbols like net portals and ground). I’ve included quantities and each component’s purpose.

Summary

30 × WS2812B addressable RGB LEDs
31 × Generic Capacitors (30 local decouplers + 1 bulk input cap)
1 × Generic Resistor (data series resistor)
2 × Samtec TSW-103-07-G-S 3-pin headers (IN/OUT)

Notes

Utility symbols not included in BOM: net portals and GND.
If you want, I can add capacitor values/voltage ratings and a specific resistor value, then re-run parts availability to prep for ordering.
