v0.3.0

• cloneFit: 'freeze' | 'scale' — 'scale' scales the frozen source clone to the blob's border box every frame instead of holding it at the source's pixel size, so a photo keeps growing rather than dissolving. Paired with cloneFadeUntil: Infinity you get a continuous morph with no empty-box phase.
• handoff: 'fade' | 'hard' — 'hard' collapses the target's opacity ramp and the blob's fade into one instant at revealAt, for a clean switch when the two ends don't line up pixel-for-pixel (cover-cropped thumbnails).
