Overcoming Our Primitive Obsessions
summary
Shows how replacing primitive strings with richer types reduces bugs and duplicated rules: use a SKU value object to enforce length/currency, a Category enum that embeds color, and remove scattered Twig extensions/managers. Adds PHPStan architecture checks to catch wrong types so validation lives in one place; adding a new category becomes a small localized change instead of edits across many files.
