const COLS = 131;
const ROWS = 541;
= 212,613 pixels
Re: pixels - the code uses cells (windows?) in 2x2 blocks with 1px gaps, giving only 3x131x541 = 212613. Not raw canvas pixels.

Spoilers below for the completed tower appearance:
Fold out to see Towers (as they will solve to, if it does not change)
white = player window & cyan = structural:
| Tower | Index range | Prime count | First prime | Last prime |
|---|---|---|---|---|
| Blade 1 | 1 – 70,871 | 7,016 | 2 | 70,867 |
| Blade 2 | 70,872 – 141,742 | 6,146 | 70,877 | 141,731 |
| Blade 3 | 141,743 – 212,613 | 5,856 | 141,761 | 212,593 |
| Total | 1 – 212,613 | 19,018 | 2 | 212,593 |
The very first window pixel (index 1 = prime 2) and the very last window pixel (index 212,613 = prime 212,593) are both white/player windows. The building is bookended by player windows.
