 * The page renders albums and essays from several branches — subpage album,
 * essay, single-album subpage, standalone album — and each one passes the
 * proofing props by hand. The dialog hides its email button without a
 * recipient (#736), so a branch that forwards `allowMailto` but forgets
 * `encodedMailto` silently loses the button on that kind of page. #746 missed
 * two of the four; this keeps the next branch from doing the same.
