One concept.
A day.

The basics fade when AI writes the code.
Five minutes a day keeps them sharp.

Morning. Coroutine cancellation is ready.

AI writes more of the code every year. The why is still yours to keep.

Autocomplete is great until a review, an outage or an interview asks why. One fundamental a day, made to stick.

Built to remember, not just to read.

Reviews that come back
