phy-css-dead-code

Unused CSS detector and dead selector auditor. Scans your stylesheet files against all HTML, JSX, TSX, Vue, and template files to find selectors that are defined but never referenced anywhere in your codebase. Detects CSS framework (Tailwind, Bootstrap, CSS Modules, vanilla CSS, Sass/SCSS) and applies the right analysis strategy for each. Reports estimated byte savings per dead rule, finds !important overuse, duplicate selectors, and orphaned media-query blocks. Generates a safe-deletion plan with exact grep verification commands. Works with PostCSS, Sass, Less, and raw CSS. Zero external API
