/* ---------- a plate that BLEEDS ----------
   Opt-in, and only when the block asks for it. Every rule above is left
   exactly as it was and none of them is overridden except through the
   .bleed class, so the two books already built with mounted plates render
   character for character as before.

   The difference is what the picture is FOR. A MOUNTED plate is an
   illustration laid ON the page with paper showing round it. A BLED plate
   IS the page: it runs to all four edges, and the caption therefore has no
   paper of its own to stand on, so it has to stand on the picture. Two
   consequences follow that the mounted rules never have to deal with.

   FIRST, object-fit HAS TO BECOME cover. `contain` fits the whole picture
   inside the leaf and leaves bars wherever the proportions disagree -- and
   on a bled plate those bars are the one thing the mode exists to abolish.
   `cover` fills the leaf and crops the overflow instead. That is a real
   cost, paid knowingly: a plate materially wider or narrower than the leaf
   loses its edges. The plates this was built for are portraits within a few
   per cent of the leaf's own proportion, so the crop is a sliver off the
   head and foot and no figure is cut.

   SECOND, the caption NEEDS ITS OWN GROUND. Light type over an unknown
   picture is legible on one plate and invisible on the next, so the caption
   carries a gradient scrim: opaque at the foot, clear a short way up, dark
   enough at every point in between that the words hold. The scrim is a
   background ON THE CAPTION BOX rather than a separate element, so it can
   never drift away from the words it exists to carry. */

/* ---------- the sand sequence on a part page ----------
   Three stages, in this order: the Book's title fades in letter by letter,
   the letters blow away downwind, and the numeral resolves in the space they
   leave. build.py bakes each letter's two delays and its own drift into
   inline custom properties, so the stagger is scaled to the length of the
   title and every Book page runs to the same clock however long its title is.

   The title is laid over the whole leaf rather than stacked above the label,
   so the numeral appears exactly where the title was standing rather than
   somewhere underneath it. Words are inline-block: a line may break between
   words and never inside one.

   Note on the two animations per letter. sandOut is declared with `both`, so
   during its delay it holds its own first frame -- and its first frame is the
   fully-arrived letter, which is precisely what sandIn finished on. That is
   what lets the two run back to back on one element without the second one
   wiping out the first while it waits. */
/* Tracking and word space have to be set against each other. These titles

   the tracking -- at .12em of tracking against a .42em gap the two readings

/* The word-space, and why it is a margin rather than the flex gap above.
   The letters are wrapped in one aria-hidden span so a screen reader gets the
   title once from the container instead of spelling it out. That wrapper is
   the ONLY child of the flex box, so flex gap had nothing to apply between --
   and because the builder joins the word spans with no whitespace at all,
   there was no word-space in the markup either. The words were separated by
   precisely the trailing letter-spacing of their last letter, which is to say
   by exactly the same distance as the letters inside them, which is exactly
   what a reader reported: you could not see where one word ended.

   display:contents lifts the words back out to be the flex items, and the
   margin gives them a word-space that holds whatever layout context they end
   up in. Belt and braces on purpose: this went wrong once already. */

/* ---------- The Magic Ring, Vol. III: the chapter half-title leaves --------

   THE SAME TREATMENT AS THE FIRST TWO VOLUMES, IN THIS VOLUME'S OWN INKS.
   Twenty-eight titles, sentences again -- "How Sir Folko fought with an old
   woman, and broke her stand of crockery-ware" -- so each has a leaf to
   itself and the duplicate over the prose is not painted at all.

   THE MOTION IS TYPE AND NOTHING ELSE. The engine's .chapanim stage stays
   empty; the only things that move are the numeral, the hairline and the
   title.

   WHY EACH RULE IS A TWO-ANIMATION SHORTHAND. book.css already gives these
   three spans a staged entrance keyed to .play, and `animation` is a
   shorthand: a rule naming only a loop would REPLACE that entrance rather
   than join it, and the leaf would arrive with its lettering already sitting
   there -- which looks exactly like a finished page and is not one.

   THE PERIODS, AND THE ONE THAT ALMOST GOT MISSED. 13.70s, 16.10s, 19.30s.
   They are distinct from each other; none of them is one of the fifteen the
   engine stylesheet ships; none is volume one's or volume two's. AND NONE IS
   ONE OF THIS BOOK'S OWN COVER PERIODS -- which is a constraint nobody in
   this series had written down before, because the cover stylesheet and the
   leaf stylesheet are two files but ONE document: build.py appends both into
   the same <style>. A leaf that breathes on the same period as the harp's
   gleam is two unrelated things falling into step, which is the exact fault
   the out-of-phase rule exists to prevent. The first two volumes happen to
   clear their own covers by luck; all three suites now check it.           */
