deck-page-edges (thing): the Thing header and footer take one frame
variable equal to .page's outer width, the footer neuters the engine's
min-width, and the ticker band and confidentiality line move into the
stage's flow under a min-height stage so they cannot lie over the hero.
ritual-phone-width (site-masthead): the ritual essays' .center rule is
deleted; its 1120px cap was dead on desktop and made the column
shrink-to-fit the cover's code blocks on phones, pushing the nav off
screen. Re-measured live: the h1 was not the cause.
