Gridpaper: Scientific figures in the browser (gnuplot, WASM)

Running gnuplot entirely client-side is the selling point — you get real gnuplot scripting and instant previews without a backend. The examples gallery and interactive parameter controls (e.g. temperature sliders, harmonics/orders) show it’s built for exploration and teaching, not just one-off charts. It’s not trying to out-Plotly Plotly; it instead gives existing gnuplot users a ridiculously convenient, portable playground.
