0.11.4 — granted and shown are two moments

The time threshold is usually crossed mid-reading — after a minute or two on a longer entry. The mark is created then, and that is right, because we measure time rather than arrival at the end. The trouble starts only with showing it.

**A mark that leaps above the text mid-paragraph takes away precisely what it was granted for.** The person looks up, loses the sentence, comes back. A reward for reading that gets in the way of reading contradicts itself — however well it is made.

**From this version, granting and showing are two different moments.** The mark is created quietly, when the threshold is crossed. The animation waits. A sentinel sits just below the last paragraph; when it drifts into view, the text is over.

**Anyone who does not reach the end will not see the mark this time.** And that is fine: it is in the database and will show on the next visit. Nothing is lost, only the moment of hearing about it moves.

One question this version closes too early: whether the end of the text is really proof that the reading has ended. On a short entry and a tall screen the sentinel drifts into view while the reader is still reading. That surfaces two versions later.
