Configure kit.csp (mode auto) so SvelteKit nonces its own scripts and script-src can stay free of 'unsafe-inline'. style-src keeps 'unsafe-inline' for the preview's dynamic inline style attributes. Allowlist covers Google Fonts, GA, Tally, and the example-previews CDN. Move the GA gtag bootstrap out of app.html into bundled JS (deferThirdPartyScripts) so the page ships no inline script. Add a /api/csp-report endpoint that logs violations while running report-only. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
QA passed in report-only mode; switching to enforcing. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
