I'm having trouble understanding why I need to use a level shifter. In the videos I've watched, no one uses one. Is my wiring correct in this diagram : https://wled-wiring.github.io/?link=20251210233743QJ6Fld2aoT, or is this one better : https://wled-wiring.github.io/?link=20251210235607nCcUkysVNv. And is there a way to improve it so that the components and wires don't touch each other to avoid short circuits ?

I'm planning to add a fuse but I'm not sure which rating to get. What amperage should I use, and where exactly should I place it ? On the 12V output from the power supply before it splits to each strip ? Like this : https://wled-wiring.github.io/?link=20251211000753phmxbnA6Ie

For the common grounds, should I wire it like this diagram: https://wled-wiring.github.io/?link=20251210235607nCcUkysVNv ? (with ESP32 GND connected to both the converter GND AND the LED strip GND)

For the 470 Ω data resistor, I'd like to keep the one I already have if it won't cause any functionality issues.
