Why do build tools emit CSS files with content hashes (`app.3f9a1c.css`)?

✓Correct answer: So files can be cached "forever" (immutable) while every change gets a new URL
2To obfuscate the CSS
3To make files smaller

Explanation

The HTML referencing the file is short-lived; the asset itself never changes under the same name. This avoids users getting stale styles after a deploy.
