|
||||
focus-swap: HyperFrames video primitive (ui-props / holdable / demonstrate)
|
||||
|
||||
Concept: attention moves between two side-by-side cards. The card losing
|
||||
focus recedes to 0.92 scale, softens, and dims while the other card advances
|
||||
to full scale, sharpness, and opacity. Both sides move together as one clean
|
||||
swap.
|
||||
|
||||
Compiled-from evidence: launches-motion-vocabulary.md section 3.6 identifies
|
||||
blur-focus / defocus in 14 of 18 production launches and names focus-swap as
|
||||
a high-frequency missing primitive for blur + opacity + optional scale.
|
||||
|
||||
Use when: directing the viewer from one product state, option, or result to
|
||||
another without moving either element out of its established layout.
|
||||
|
||||
Variables:
|
||||
- focus ("a" | "b", default "b"): the card that ends focused.
|
||||
- blurPx (number, default 6): blur applied to the unfocused card.
|
||||
- dim (number from 0 to 1, default 0.5): unfocused card opacity.
|
||||
|
||||
Envelope (holdable):
|
||||
IN = 0.90s at the standard duration, including a 0.20s readable lead.
|
||||
HOLD = elastic and deliberately still after focus lands.
|
||||
OUT = none; the host composition owns the cut or exit.
|
||||
For durations under 0.90s, the lead and swap compress to finish by D.
|
||||
|
||||
Sync point: focus-landed at 0.90s into IN at the standard duration. It
|
||||
compresses with IN only when D is shorter than 0.90s and never enters HOLD.
|
||||
|
||||
Sound: none. This continuous attention shift has no discrete impact cue.
|
||||
|
||||
Mount contract: this is a template-wrapped sub-composition. The runtime
|
||||
clones only template contents. #root has no data-width or data-height and
|
||||
fills the host-owned box with position:absolute, inset:0, and
|
||||
container-type:size. The paused GSAP timeline is registered under the
|
||||
hardcoded composition id "focus-swap".
