* [Keyboard] Kinesis + Pro Micro init - docs for DIY - custom matrix = lite - a near-factory dvorak mapping - optimized debouncing for lower latency * chore: reformatting * chore: update doc * chore: cleanups according to PR feedback * chore: PR feedback * fix: compile error * chore: add include * fix: LEDs hanging after USB disconnect * chore: enable QMK goodies by default * chore: use semantic write pin
