    Recursive Habit — Neon Math Code Design
    A neon-lit programmer's take on habit-building: "recursive habit" in bold bracket notation, paired with the recurrence formula x(n+1) = x(n) + Δ and the line "not much today, everything eventually." Part code joke, part self-improvement mantra, styled like a glowing sign against a dark background. A sharp gift for programmers, engineers, and anyone who appreciates that real progress is just small updates run over and over.
