before list of changes, i just wanna say that the hardest part is wrapping my head around the bit shifting logic and figuring out how to represent moves and pieces in a single integer. because the main focus of this is gonna be performance so that i can build a chess bot on top of this and have decent speeds.

anyways:

• optimized piece enum to use 1 less bit for color
• use bit shifts in piece.color to better understand
• rename utils.ts to game.ts and update imports
• tweaked enums to integrate more with the movegen system im going to implement
• added Promotion, Capture, and MoveFlag enums

not much changes to the ui so here is screenshot of the code
