C1: cssPropsToString emitted the camelToKebab'd style-object KEY unsanitized while only sanitizing the VALUE. A malicious style key containing a quote (reachable via AI update_props or deserialized saved state) could close the style="..." attribute and inject a live element. Now validates each key against a CSS property/custom-prop allowlist and drops anything that doesn't match. C2: buildDataAttrs (html-export.ts) interpolated props.animation and props.animationDelay directly into data-animation="..."/ data-animation-delay="..." with no escaping, for every exported node. Now routes both through escapeAttr. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
