Sharing Your Rebuild Card
Your speed is the proof. The card makes the pattern-match visible.
The card: your fastest clean rebuild (the sentence you spelled without a single miss), your most-missed letter, and the total time from first tap to last. It is a speed record, not a quiz score - because the format is a performance, and the performance is the speed.
Why it is shareable: a speed record has a natural challenger. "Beats me - I got it in 4.2 seconds" is the follow-up that turns one card into a small competition. The card is the opener; the reply is the share.
The honest detail: the card also prints the moment you misread - "your brain grouped 'sub' as 'sh b' for half a second". That self-awareness is the part people screenshot, because it is the format's whole joke made concrete.
