/* gmail-mcp owner console.
   The CSP is default-src 'none'; style-src 'self', so there is no script, no webfont and no image
   here by design: every texture below is drawn with gradients and every face is one the machine
   already has. The look is an audit ledger rather than a dashboard, because that is what these
   pages are: a record of who was trusted with what, and a place to refuse. Saturated colour is
   spent only on risk, so that when something is red it means something. */
