• The linked issue requires QR-code inversion to be enabled only when the theme's darkMode setting is active, but this rule neither inverts the image nor checks the pf-v5-theme-dark class that template.ftl conditionally adds. As written, dark-mode QR codes retain their light rendering, while child themes with darkMode=false still lose the border and shadow based solely on the OS preference.

@media (prefers-color-scheme: dark) {
    .kc-qr-code img {
        border: none;
        box-shadow: none;
    }

• This visible alt text is hard-coded in English, so non-English credential-offer pages expose an untranslated description to screen-reader users. Add a credential-offer-specific message key to the bundles and pass it through msg(...), as the TOTP and OID4VP QR-code call sites do.

                <@qr.qrCode id="kc-credential-offer-qr-code" content=credentialOffer.qrCode alt="QR code to claim a credential with a wallet">

• The dark-mode rule never inverts the QR image as required by #51450, and using the media query directly bypasses the darkMode template-variable gate. Target the class that template.ftl adds only when dark mode is enabled and apply the inversion there.

@media (prefers-color-scheme: dark) {
    .kc-qr-code img {
        border: none;
        box-shadow: none;
    }

• The dark-mode rule is driven directly by the OS media query and never inverts the QR image, so it is neither gated by Keycloak's darkMode setting nor does it meet the linked issues' QR inversion requirement. Target the class that template.ftl adds only when dark mode is enabled and apply the inversion there.

@media (prefers-color-scheme: dark) {
    .kc-qr-code img {
        border: none;
        box-shadow: none;
    }
