The code returns the following error:
A tree hydrated but some attributes of the server rendered HTML didn't match the client properties. This won't be patched up. This can happen if a SSR-ed Client Component used:
- A server/client branch `if (typeof window !== 'undefined')`.
- Variable input such as `Date.now()` or `Math.random()` which changes each time it's called.
- Date formatting in a user's locale which doesn't match the server.
- External changing data without sending a snapshot of it along with the HTML.
- Invalid HTML tag nesting.
It can also happen if the client has a browser extension installed which messes with the HTML before React loaded.

Revise the code to address the error.
I was previewing: /
The hydration error is caused by Math.random() in the bubble generation, which produces different values on the server vs client. I'll replace the random values with deterministic, pre-computed bubble data.
The hydration mismatch was caused by Math.random() generating different values on the server and client during rendering. I replaced the random bubble generation with a pre-computed BUBBLES constant array containing deterministic size, position, duration, and delay values, ensuring identical output on both server and client.
The code returns the following error:
Uncaught ReferenceError: BUBBLES is not defined
at Hero (components/hero.tsx:35:10)
at Set.forEach (<anonymous>)
at Home (app/page.tsx:18:7)

Revise the code to address the error.
I was previewing: /
The file looks correct - the BUBBLES constant is defined at line 13 before Hero uses it at line 47. The error references components/hero.tsx:35:10, which suggests the runtime may be using a cached/stale version. Let me force a re-save of the file to ensure the latest version is picked up:
The code was already correct with BUBBLES defined as a module-level constant before the component. The error was referencing a stale cached version at the old line number (line 35 instead of the updated line 47). Re-saving the file forces the bundler to pick up the latest version with the BUBBLES array properly in scope.
