Notes from the workbench.

What goes inside a Contao 5 bundle, from composer.json to Twig templates and migrations, and how we decide whether a feature needs an extension at all.

A dashboard is only useful if people believe it. How we built one where every figure has a written definition and can be checked against the raw data.

AI coding assistants multiply what a developer can finish. They also write confident, plausible, wrong code. Experience and a few habits are what catch it.

A spreadsheet is a fine first version of a process. The signs that one has outgrown itself, and how we replace only the part that keeps breaking.

What changes when a Contao site moves to 5.7: wrapper classes, figure markup, Twig templates, Isotope migrations, and the process we use so the site looks the same afterward.
