aurora-drift: HyperFrames video primitive (backgrounds / ambient)
|
||||
|
||||
Concept: three oversized, softly blurred accent-derived fields drift over
|
||||
a deep base beneath a faint vignette. The motion stays slow and restrained,
|
||||
giving a scene color and depth without competing with foreground content.
|
||||
|
||||
Variables:
|
||||
- accent (green | blue | violet, default green): selects the source token
|
||||
from which the three related aurora hues are mixed.
|
||||
- mood (deep | bright, default deep): controls base luminance and field
|
||||
strength while preserving the same motion.
|
||||
|
||||
Envelope: IN = 0, HOLD = the full elastic duration, OUT = 0. The phase proxy
|
||||
advances through exactly one whole sine cycle during HOLD. A longer mount
|
||||
stretches only that ambient cycle.
|
||||
|
||||
Loop invariant: phase 2 * PI is normalized to phase 0 before any transform
|
||||
is calculated, so every blob has exactly the same pose at t=0 and t=duration.
|
||||
|
||||
Sound: none.
|
||||
|
||||
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 hardcoded aurora-drift id.
