A Dash cookbook for huge, multichannel time series: from toy labeling demo to lab-deployed desktop app

I present Time Series App Cookbook — a runnable Dash template for navigating and annotating recordings of millions of points without lag, built on plotly-resampler. The demo makes 2.7M synthetic samples, so you can feel the speed. The README is the cookbook: 18 recipes, each saying what a feature does, how it works, and what breaks if you change it.
