   As explaind in $811 RainbowKit renders the WalletConnect QR with cuer@0.0.3, which calls encodeQR(..., { border: 0 }) and declares its QR dependency as "qr": "~0", so any 0.x version is accepted. Since qr@0.6.0, encodeQR throws RangeError: invalid border=0. The lockfile refresh in #788 bumped qr from 0.5.5 to 0.7.0, so opening WalletConnect on desktop crashes the page. Mobile uses a deep link and never renders the QR, which is why it kept working there.

   Upstream: rainbow-me/rainbowkit#2677, still open. RainbowKit 2.2.11 and cuer 0.0.3 are the latest versions, so there is no upstream release to move to yet.

   Fix: #811 overrides cuer@0.0.3>qr to 0.5.5. The override stops applying once RainbowKit ships a newer cuer, so it won't linger past an upstream fix.
