   build-pages.py and staggers the four.

   This is a keyframe animation rather than a from-class plus a to-class on
   purpose. The two-class version needed requestAnimationFrame to reach the
   visible state, and rAF does not fire while a tab is unpainted or
   throttled — so a switch made off-screen left the cards stuck at zero
   opacity. An animation with `backwards` fill holds the from-state only for
   its own delay and always lands on the element's real styles, so the worst
   case here is no animation rather than no content. */

   a line of its own, and it is not needed: measured across every word in the
   list, at 375px and up, the headline keeps one height and never overflows —
   the phrase is short enough that no word changes the line count. The word
   growing in place after "your" is also the effect itself. */

/* The rotating word gets a line to itself.
 *
 * It used to sit inline after "your", so every few seconds a longer word
 * wrapped the headline onto an extra line and the entire page below it
 * jumped. A character cap tried to hold that off, which only narrowed the
 * widths where it broke. On its own line the word cannot change how the
 * static text above it wraps, at any width or any length.
 *
 * min-height holds the line box open while the word is empty — the script
 * erases to "" between occasions, and without this the line collapses and
 * the page jumps exactly once per cycle, which is the bug this fixes. */
