+ *
+ * Usage:
+ *   node live-accept.mjs --id SESSION_ID --discard
+ *   node live-accept.mjs --id SESSION_ID --variant N
+ *
+ * For discard: removes the entire variant wrapper and restores the original.
+ * For accept: replaces the wrapper with the chosen variant's content. If the
+ * session had a colocated <style> block, it's preserved with carbonize markers
+ * for a background agent to integrate into the project's CSS.
+ *
+ * Output: JSON to stdout.
