⚠️ Potential issue

🧩 Analysis chain

Switched to '@tailwindcss/postcss' — required for Tailwind v4. LGTM.

Config shape is valid ESM under "type":"module".

Run to ensure no other packages still use the old tailwindcss PostCSS plugin:

🏁 Script executed:

#!/bin/bash
# Find all PostCSS configs and flag legacy plugin usage.
set -euo pipefail
fd -H -a -t f 'postcss.config.*' | while read -r f; do
  echo "== $f =="
  rg -nC2 -P "(tailwindcss:|require\\(['\"]tailwindcss['\"]\\))|@tailwindcss/postcss" "$f" || true
done

Length of output: 304

Update examples/react-router/postcss.config.js to use '@tailwindcss/postcss'
examples/react-router/postcss.config.js still contains tailwindcss: {} (line 3); replace it with @tailwindcss/postcss: {} so all PostCSS configs use the Tailwind v4 plugin.

🤖 Prompt for AI Agents 
In dashboard/postcss.config.js around line 3, the PostCSS config uses the old
key `tailwindcss: {}`; update that entry to use the Tailwind v4 plugin key
`@tailwindcss/postcss: {}` so the file matches other PostCSS configs. Replace
the `tailwindcss` property name with `@tailwindcss/postcss` and keep the same
config object contents.
