- Updated all nine BetterPhotos Sass/build-tool dependency sets and lockfiles.
- Replaced the obsolete csso CLI pipeline in lectures 28 and 29 with current PostCSS/cssnano tooling. Use
npm run build; the individual build commands remain available. - Added Node.js 24 guidance, weekly dependency-update pull requests, dependency-audit/build checks and educational/security notices. These changes deliberately deviate from the recordings.
- Verification: all nine stylesheet compilations and both prefix/minification pipelines passed; all nine package audits reported zero known vulnerabilities at review time.
See SECURITY.md before use. Static stylesheets do not make a deployed website secure, and future advisories require review.
