src/uSupport/Views/Partials/uSupport/Emails/NewTicketEmail.cshtml:49

• @Html.Raw(Model.Summary) renders unencoded HTML into the email body. Even if the summary is usually sanitized, this bypasses Razor’s default encoding and can lead to HTML/script injection in outgoing emails if any unsanitized content reaches Summary (e.g., through updates/migrations). Prefer keeping Razor encoding (or sanitize/whitelist HTML at render time before using Html.Raw).
  src/uSupport/Views/Partials/uSupport/Emails/UpdateTicketEmail.cshtml:89
• The comments table is now only rendered when Model.Comments.Count() > 1. If there is exactly 1 comment (or 0), the entire "Comment" section will be empty. This looks unintended for update emails; render the table whenever there is at least one comment (or render a fallback message when there are none).
  src/uSupport/Views/Partials/uSupport/Emails/UpdateTicketEmail.cshtml:80
• The isLast padding logic appears inverted: previously padding was applied to non-last rows to create spacing, but now padding-bottom: 25px; is applied only when isLast is true. If the intent is spacing between comment rows, apply padding to the non-last rows (or rename the variable to reflect the intended condition).
