A private, offline typing trainer that scores you the way an employment
assessment does — then tells you which keys cost you the score and
builds an exercise out of them. Runs are forward-timed: the clock counts up
and your completion time on a fixed, stored passage is the score, so this
week's 41.2s against last week's 47.9s is a real
measurement, not a rate against an arbitrary countdown.
Every exercise is stored and re-runnable, with records kept per mode
(passage, word bag, countdown) and per-key diagnosis feeding drills built
from your own weak spots. Native Rust/egui desktop app, bootstrapped from
rust-skeleton — nothing leaves the machine.
