# FIX-160 — Architect

## Problem
POS app (apps/pos) hydration mismatch: LastPass browser extension injects `data-lt-installed="true"` on the `<html>` tag, causing React to warn about server/client HTML mismatch.

## Fix
Added `suppressHydrationWarning` to `<html>` tag in `layout.tsx`. Same fix already applied to admin app (FIX-001).
