Analyzing the PCB layout.

Most congested routing area
The densest cleanup zone appears to be the power-harvester cluster in the left-middle of the board, roughly:

Table


RegionApprox. areaWhy it looks worst
Energy harvester / storage sectionX ≈ -16 mm to 0 mm, Y ≈ 15 mm to 21 mmMany short trace segments, vias, and tight fanout concentrated around the boost/PMIC network

Components concentrated there


Components
U57, L90, C1, C2, C3, R5, R6, R7, D6

Secondary congested area


RegionApprox. areaNotes
USB / regulator cornerX ≈ -4 mm to 7 mm, Y ≈ 22 mm to 39 mmDense vertical routing around J4, U6, C21, C22, C23, C24

Lowest-priority congestion


RegionNotes
RF side near U3, J1, and J2More open overall than the harvester section
Recommended cleanup order
  1. U57 power-harvester cluster
  2. J4 / U6 USB-regulator area
  3. RF section last
If you want, I can next turn this into a specific reroute checklist by component/net.

Checking if I can make the changes for you.

I can apply that PCB cleanup action next:
  • Rework the layout toward the intended 2-layer, RF-aware ruleset
  • Prioritize cleanup in the power-harvester cluster
  • Then clean up the USB / regulator area
  • Then address the RF section
Proceed with the layout-rule rewrite when you're ready.
