 ## Notes
-- Lead with the hook, not the tech — the "it hid a gift" turn is the whole post.
-- The em-dash framing ("a word I never taught it") is the load-bearing line; keep it.
-- If the platform requires tagging the hackathon org/account, add it to the first line.
+- Lead with the turn ("it hid a gift"). The technical hook is the second beat, not the opener.
+- The lowercase, casual register is deliberate; keep it conversational, not announcement-y.
+- Attach the clip or the finale screenshot, and link the Space from the post.
