E_CSP_NONCE
An inline script or style has no nonce
The page writes a <script> or <style> inline without the nonce the Content-Security-Policy announces. The browser refuses to run it, so the page passes a test that only reads the HTML and breaks on the screen.
Fix
Write it with trilha.NonceAttr(c) — h.Script(trilha.NonceAttr(c), h.Raw(js)) — or move the code to a file under public/ and load it with src. `trilha audit` points at the page; PageSnapshot.HasCSPNonce checks the served HTML.
h.Script(trilha.NonceAttr(c), h.Raw(js))
