+Vulnerability: Cross-Site Scripting (XSS) via unescaped gRPC channel error messages rendered using template.HTML.
+Learning: Manually constructing HTML strings in Go code and casting them to template.HTML is inherently risky and bypasses built-in contextual escaping.
+Prevention: To prevent XSS, use structured data types (e.g., slices of structs) to pass data to HTML templates, allowing the html/template engine to handle contextual auto-escaping safely during rendering.
