When Svelte components inject `<style>` elements at runtime via `append_styles`, these elements now inherit the CSP nonce from any existing nonce-bearing element on the page. This allows them to pass CSP checks when a `style-src 'nonce-...'` policy is in effect. Browsers expose `element.nonce` to JavaScript while hiding it from CSS selectors, so querying `[nonce]` and reading `.nonce` is safe and works correctly.
