Bust every hand and the dealer doesn't draw, which is right, but it was also
not turning over: reveal is only emitted by dealerPlay, and busting out skips
the dealer entirely. The browser kept the hole card face down while the settled
state printed the dealer's whole total under it. Emit the reveal on that path.
And standing your bet back up after a reload read the hand's bet straight off
the settled state, which a double has already doubled. Reload, double 200, and
the next hand starts with 400 on the spot.
Plus: the share card was hand-writing a Content-Length that ServeContent
overwrites anyway, and serving a zero-byte 200 for a room with no card.
