The code returns the following error:
Uncaught Error: Hydration failed because the server rendered text didn't match the client. As a result this tree will be regenerated on the client. 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 mismatch is caused by the special characters (ã, ô, í) being encoded differently between the server and client. I'll use Unicode escape sequences to ensure consistent rendering.
Now let me check the other components for the same issue:
The other components also contain accented characters that could cause the same issue. Let me fix them all:
The hydration mismatch was caused by accented Portuguese characters (like ã, ô, í, ç) being encoded differently between the server and client renders. I replaced all accented characters across the four components with their explicit Unicode escape sequences (e.g., \u00E3 for ã), which ensures byte-for-byte consistency during hydration. This fix covers the footer, hero section, services section, and WhatsApp button URL.
The debug logs show the error is still referencing the old file content with literal accented characters ("Porto Alegre e Região (51) 9491-1768" vs "Porto Alegre e Regi�o (51) 9491-1768"). The current source code already has the unicode escapes, so this is likely a stale build cache. However, the root cause is deeper -- the SiteFooter has no "use client" directive but the WhatsAppFloatingButton does. The Page component is a Server Component rendering both.
Looking more carefully at the error, the removeChild error and the hydration mismatch suggest the issue is that WhatsAppFloatingButton is a client component marked with "use client", which is fine. But the real problem is the file encoding. Let me rewrite the files to ensure they're saved with clean ASCII-only content, and also let me read the original attachment to make sure I'm faithfully recreating the design:
Now I see the full picture. The original component is a single client-side component. The real issue is that splitting it into Server Components is causing encoding mismatches for Portuguese characters during SSR. The simplest and most robust fix is to make the entire page a Client Component, matching the original design intent. This eliminates the SSR/hydration character encoding issue entirely.
Now let me clean up the separate component files that are no longer needed:
The root cause was a character encoding mismatch during SSR hydration -- the server rendered Portuguese accented characters (like ã, ô, ç) differently than the client expected. I consolidated everything into a single "use client" page component, matching the original design's architecture, and used Unicode escape sequences (\u00e3, \u00f4, etc.) for all accented characters. I also percent-encoded the accented characters in the WhatsApp URL to avoid the same issue there. The separate component files have been cleaned up since they're no longer needed.
