What happened?

When a .css file does a bare-package @import whose target requires package.json#exports resolution (instead of mapping to node_modules/<pkg>/<file> directly), fallow reports it in unresolved_imports even though the file exists and bundlers resolve it correctly.

Concretely, on fallow 2.62.0 and the published shadcn@4.6.0:

/* apps/web/src/index.css */
@import "shadcn/tailwind.css";

is reported as:

{
  "path": "apps/web/src/index.css",
  "specifier": "shadcn/tailwind.css",
  "line": 1
}

The actual file lives at node_modules/shadcn/dist/tailwind.css and is exposed only via the package's exports map under the style condition:

{
  "exports": {
    "./tailwind.css": { "style": "./dist/tailwind.css" }
  }
}

Tailwind v4 / Vite / PostCSS resolve this correctly. Fallow's CSS resolver appears to look up node_modules/shadcn/tailwind.css directly without consulting exports, so it can't find the file.

This is distinct from #252 (closed v2.60.0), which fixed bare-package CSS imports whose target sits at node_modules/<pkg>/<file> with no exports indirection.

Reproduction

mkdir repro-css-exports && cd repro-css-exports
cat > package.json <<'PKG'
{ "name": "repro", "private": true, "dependencies": { "shadcn": "4.6.0" } }
PKG
npm install
mkdir src
echo '@import "shadcn/tailwind.css";' > src/index.css
cat > src/entry.ts <<'TS'
import "./index.css";
export const main = () => {};
TS
cat > tsconfig.json <<'TSC'
{ "compilerOptions": { "module": "esnext", "moduleResolution": "bundler" }, "include": ["src"] }
TSC
fallow dead-code --format json --quiet

Output contains:

"unresolved_imports": [
  { "path": "src/index.css", "specifier": "shadcn/tailwind.css", "line": 1, "col": 0, "specifier_col": 0 }
]

Verify the file is real:

ls node_modules/shadcn/dist/tailwind.css   # exists
node -e 'console.log(require("shadcn/package.json").exports["./tailwind.css"])'
# { style: './dist/tailwind.css' }

Expected behavior

CSS resolver follows package.json#exports (honoring the style condition, falling back to default) the same way Vite / Tailwind v4 do. Specifier should resolve to node_modules/shadcn/dist/tailwind.css and not surface in unresolved_imports.

Secondary bug (same repro)

When shadcn is added to ignoreDependencies to silence the cascading "unused dep" finding, the dependency is correctly filtered from the unused_dependencies array but the summary.unused_dependencies count is not decremented. total_issues and the array contents disagree:

"total_issues": 2,
"summary": { "unused_dependencies": 1, "unresolved_imports": 1, ... },
"unused_dependencies": [],         // empty
"unresolved_imports": [ ... ]      // 1 entry

Happy to split into two issues if preferred.
