Verdict

The table studies together. Same-evening patch on Joe's rule for multiplayer ceremony pacing:

• With two or more humans seated, the roll screen holds for its full 30 seconds — nobody can click past it, so the whole table studies the same fates together and nobody's spoils go half-read because an opponent clicked first. Clicking still flips the cards face-up early (that accelerates the animation, not the study window), and the countdown measures from when the ceremony opened so it ends in step with the server's clock hold. A lone human against bots keeps the old click-through, offline and online alike.
• Server: the opening clock hold goes 25 → 30 to match, and AuthResult now carries human_seats (serde-defaulted both ways — old client and old server each degrade to the previous skippable behavior).
