 * Intentionally empty. Hosting answers /content/theme.css with this file
 * (fleet/firebase.json), so a public screen's page load finds the content
 * bundle's theme link a valid, empty stylesheet instead of the app shell, which
 * nosniff refuses as a stylesheet (a console error on every load).
 *
 * An appliance never reads this: its nginx serves /content/ from the device's
 * own content bundle before it looks in the web root.
