Type Match Cut - HyperFrames

Install

That writes one file: compositions/components/type-match-cut.html.

Paste it into your composition

Open compositions/components/type-match-cut.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`	`Meet the new editor`	string	Text split around the incoming panel.
`accent`	`green`	`green`, `blue`, `violet`	Accent color used by the incoming editor scene.

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="type-match-cut"
  data-composition-src="compositions/components/type-match-cut.html"
  data-variable-values='{"text":"Meet the new editor","accent":"green"}'
></div>

  type-match-cut: HyperFrames video primitive

  A headline splits into upper and lower word groups. An incoming editor
  panel appears in the negative space between them, holds there as a visible
  geometric match, then grows to fill the frame while the words arc through
  the top and bottom edges.

  Variables:
    text: headline copy
    accent: green, blue, or violet incoming-scene accent

  Envelope, fixed IN and OUT with elastic HOLD:
    IN_BASE  = 1.05s, words separate and expose the matched panel slot
    HOLD     = max(0, D - IN - OUT), the slot breathes almost imperceptibly
    OUT_BASE = 1.15s, the panel takes the frame while both word groups exit
    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, and has no data-width or
  data-height. One paused timeline registers under the literal type-match-cut
  key.
