Per Word Rise

That writes one file: compositions/components/per-word-rise.html.

Paste it into your composition

Open compositions/components/per-word-rise.html and copy what is inside into your own composition. A component has no size or duration of its own. It takes both from the composition you paste it into.

Variables

Every one of these has a default, so the piece works untouched. Set the ones you want to change on the element:

Variable	Default	Accepts	What it does
`text`	`WORDS IN MOTION`	string	Text whose words or characters rise into place.
`split`	`word`	`word`, `char`	Animate the text as words or individual characters.
`cues`	“	string	Comma-separated seconds (from mount start) for each unit landing. Empty keeps the authored cascade rhythm.
`accent`	`green`	`green`, `blue`, `violet`	Contract accent token used for the text color.
`exit`	`none`	`none`, `fade`, `up`	Optional departure. Default none: the line holds until the frame cuts.

Set them with data-variable-values on the element that mounts it. These are the defaults, so this behaves exactly like the preview above until you change one:

<div
  data-composition-id="per-word-rise"
  data-composition-src="compositions/components/per-word-rise.html"
  data-variable-values='{"text":"WORDS IN MOTION","split":"word","cues":"","accent":"green","exit":"none"}'

  per-word-rise: HyperFrames video primitive (text effects / reveal)

  Words, or characters through the split variable, rise into place with a
  controlled cascade and a small blur-to-sharp settle. Each unit lands with
  a short overshoot-free settle tail (the final few pixels glide in over the
  closing frames instead of stopping dead), then the finished line holds
  truly still until the frame cuts (exit none) or departs with the optional
  exit variable.

  Variables:
    - text (string, default "WORDS IN MOTION"): displayed text.
    - split (word | char, default "word"): animated unit size.
    - cues (string, default ""): comma-separated seconds (from mount start)
      for each unit's landing. Empty keeps the authored cascade rhythm.
    - accent (green | blue | violet, default "green"): text color.
    - exit (none | fade | up, default "none"): optional departure.

  Envelope, fixed IN and OUT with elastic HOLD only:
    IN_BASE  = 1.45s, the full staggered rise and sharp settle (cues can
               stretch the rise phase past IN_BASE when they land later)
    HOLD     = max(0, D - IN - OUT), truly still: no drift
    OUT_BASE = 0.50s staggered departure when exit is fade or up, 0s when
               exit is none (the default: the line holds until the cut)
    If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
    The timeline is never time-scaled.

  Mount contract: the runtime clones only this template. #root fills the host
  box, establishes the container query basis, has no data-width or data-height,
  and registers one paused timeline under the literal per-word-rise key.
