1. Rename postcss.config.js to postcss.config.cjs
- Fixes CommonJS syntax in ES module project
- Allows build to complete successfully
2. Remove --production flag from Dockerfile
- Install ALL dependencies including sharp
- Sharp required for Astro image optimization
- Fixes sharp missing error
Both fixes enable successful Docker build and favicon to work.
- Astro build already copies public/ to dist/
- Separate public copy was unnecessary
- Only copy dist folder (contains everything including favicon)
- Fixes favicon 404 error
