Renovate PR Review Results

⚖️ Safety Assessment: ⚠️ Needs Manual Migration

🔍 Release Content Analysis

• Major dependency updates: Multiple transitive dependencies have major version bumps (postcss-mixins 9→12, postcss-nested 6→7, postcss-selector-parser 6→7, sugarss 4→5)
• Breaking changes: The major version increments in key PostCSS plugins indicate potential breaking changes in CSS processing behavior
• Security fixes: Unable to verify specific security fixes due to lack of accessible release notes, but dependency updates often include security improvements
• New dependencies: Introduction of tinyglobby as a new dependency replacing fast-glob and related packages

🎯 Impact Scope Investigation

• Usage location identification: postcss-preset-mantine is configured in postcss.config.cjs:3 with default empty configuration
• CSS processing impact: The preset processes Mantine CSS imports in src/index.css:6 and handles CSS custom properties throughout the React application
• Build system impact: The package is part of the PostCSS pipeline used by the custom Bun build script
• Zero direct usage: The codebase doesn't use specific Mantine PostCSS mixins or functions directly, reducing compatibility risk

💡 Recommended Actions

• Test build process: Run bun run build to verify the updated PostCSS pipeline processes CSS correctly
• Verify CSS output: Check that generated CSS maintains expected Mantine styling and custom properties
• Monitor for regression: Pay attention to CSS cascade issues or missing Mantine component styles
• Safe to proceed: The simple configuration and lack of direct mixin usage make this update relatively low-risk
