The HTML page loads external scripts and stylesheets from CDNs and fetches content from `raw.githubusercontent.com`, but no Content-Security-Policy is defined (neither via meta tag nor headers). This makes XSS exploitation easier if any injection vector is found. Affected files: index.html Signed-off-by: Trần Bách <45133811+barttran2k@users.noreply.github.com>
