// On Windows, @tailwindcss/node uses enhanced-resolve with a 4-second
// CachedInputFileSystem that can cache stale negative results (e.g. when
// Windows Defender locks node_modules). This causes intermittent
// "Can't resolve 'tailwindcss'" errors. Setting __tw_resolve bypasses
// enhanced-resolve by using Node.js require.resolve, which is reliable.
