NOTE: The firmware is for use with QMK (https://github.com/qmk/qmk_firmware), however this keyboard does not have an official commit yet. Thus, simply copy this keyboard's firmware into a new sub-folder in the "keyboards" folder and flash from there. See the QMK CLI docs for flashing the keyboard for extra help. Please note that this firmware is exceptionally early stage, and while completely functional, is relatively bare-bones.

Questions
How big is the JasonSplitErgoKeyboard Left PCB?
It measures 197.8 × 165 mm and has 2 copper layers, 1.6 mm thick.
What parts does the JasonSplitErgoKeyboard Left use?
134 parts, built around the RP2040 and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the JasonSplitErgoKeyboard Left KiCad files?
From the ToucanLog/ergo-split-keeb repository on GitHub, at the commit this page was made from: the board is kicad files/JasonSplitErgoKeyboard_Left/JasonSplitErgoKeyboard_Left.kicad_pcb and its schematic kicad files/JasonSplitErgoKeyboard_Left/JasonSplitErgoKeyboard_Left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the JasonSplitErgoKeyboard Left design in my own project?
Its repository states no licence, so its author keeps all rights: ask ToucanLog before reusing the design.
