+/* Time's backend client for a venture page. Written by Time next to index.html; the build never edits it.
+   Every call resolves to null when the backend can't help (no network, over the daily limit, or the page is being
+   checked locally), so a product uses these only for extras and works fully without them.
+     Time.save(obj)              -> a share link (string) or null
+     Time.load()                 -> the object a share link (?s=...) carried, or null
+     Time.ai(prompt, {system})   -> text from a small model, or null
+     Time.ready                  -> a promise of true when the backend answers */
