it's okay for board to be double sided by the way

Understood — I’ll allow bottom-side placement for small passives if it improves spacing, while keeping knobs, LEDs, buttons, USB-C, audio jack, MCU, codec, and PSRAM on top for usability and assembly clarity.

3/3 Review placement for overlaps and airwires-only expected DRC

Thought for 3 sec

Completed design checks — found 164 issues.

Read layout.

Thought for 6 sec

3/3 tasks completed.

Thought for a moment

Done — the board is now a compact 100 × 75 mm rounded rectangle with a 4-layer stackup.
Components are arranged logically without routing traces: pots in a neat row, LEDs in order below them, two buttons below/near the LED row, USB-C on the left edge, audio jack on the right edge, MCU/PSRAM central, codec near audio, and power near USB. I allowed small resistors/capacitors on the bottom side while keeping all user-facing parts and major ICs on top; placement checks are clean, and the remaining review items are expected unrouted airwires only.
