WELCOME, HACKERMAN.
> TOOL LIST — all 91 tools, filterable with grep>, each with a plain-English exam tip.
> MATCH DRILL — a 4-option quiz. Get a tool right twice in a row and it goes grey (mastered) and drops out of rotation. Miss it and it resets to red.
> PASSWORD — your progress is a 20-character save code at the bottom of the page. Copy it, paste it back in later — no login, no account, no backend.
> a few cheat codes are hiding in that same password footer, if you're curious.
