Description

Production build failing because Vercel detected Node.js version changed from "22.x" to "". Root cause: invalid JSON in package.json (missing comma) prevented the build system from reading engine configuration, and no .nvmrc existed to explicitly pin the Node.js version.

Type of Change

• Bug fix (non-breaking change that fixes an issue)

Changes Made

• package.json: Added missing comma after @typescript-eslint/parser entry (line 84). The invalid JSON caused the entire file to be unparseable by the build platform.
• .nvmrc: Created with value 22 to explicitly specify Node.js version for build environments (Vercel, etc.).

-    "@typescript-eslint/parser": "^8.60.1"
+    "@typescript-eslint/parser": "^8.60.1",
     "autoprefixer": "^10.5.0",

Dependencies

• No new dependencies. Node.js 22 was already in use (per engines field and prior build cache).
