⚠️ Potential issue

Pin exact Tailwind version and correct PostCSS release to avoid install failures

  1. postcss@8.5.6 has not been published on npm (latest 8.x is 8.4.x). Trying to install it will break project generation.
  2. NativeWind is extremely sensitive to the exact Tailwind major and minor version. Using ^3.4.17 risks silently bumping to 3.5/3.6 once they are released and re-introducing the incompatibility we’re fixing.
-	autoprefixer: "^10.4.21",
-	postcss: "^8.5.6",
-	tailwindcss: "^3.4.17",
+	autoprefixer: "10.4.21",
+	postcss: "8.4.35",
+	tailwindcss: "3.4.17",

Pinning all three to published, known-good versions guarantees reproducible scaffolding across package managers and CI.

🤖 Prompt for AI Agents 
In apps/cli/src/constants.ts around lines 121 to 124, the versions for postcss
and tailwindcss are not pinned to exact, published versions, which can cause
install failures and compatibility issues. Change the postcss version to the
latest published 8.x version (e.g., 8.4.x) and pin tailwindcss to the exact
known-good version (e.g., 3.4.17 without the caret) to prevent automatic minor
or patch upgrades. Also, pin autoprefixer to an exact version to ensure
consistent dependency resolution.

🛠️ Refactor suggestion

Remove unused variable or implement Unistyles support.

The hasUnistyles variable is defined but never used in the function. Either remove it if Unistyles support isn't planned, or implement the corresponding logic.

-	const hasUnistyles = frontend.includes("native-unistyles");

Alternatively, if Unistyles support is planned, consider implementing similar dependency setup logic for it.

🪛 Biome (2.1.2)

[error] 11-11: This variable hasUnistyles is unused.

Unused variables are often the result of an incomplete refactoring, typos, or other sources of bugs.
Unsafe fix: If this is intentional, prepend hasUnistyles with an underscore.

(lint/correctness/noUnusedVariables)

🤖 Prompt for AI Agents 
In apps/cli/src/helpers/setup/frontend-setup.ts at line 11, the variable
hasUnistyles is declared but never used. To fix this, either remove the
hasUnistyles declaration if Unistyles support is not intended, or implement the
necessary logic to handle Unistyles dependencies similarly to other frontend
options if support is planned.
