/* Entrance animations below deliberately omit `both`. With a fill mode the
   element holds the from-state (opacity 0) whenever the animation has not
   progressed, so anything that stops the clock -- a throttled background tab,
   a headless render -- leaves the content permanently invisible. Without it the
   element rests at its natural visible style and the animation is pure garnish.
   The staggered `.rise-1..4` classes keep `both` because they have a delay and
   would otherwise flash before starting. */
