liquid

morph="liquid" — distance-field melt (match-morph-liquid.ts).

Read the rig's notes

Each silhouette becomes a signed distance field lifted into a PILLOW (half-
thickness rising from the edge to a plateau `morph-size`). Both pillows share
one marching-cubes grid per pair; every frame it holds their blend plus a swell
and a seeded wobble, polygonised into a clear-coated solid lit by the scene.
Every element melts into a glossy blob that flows to its partner and sets.
Grids cost per pair per frame: ten pairs at the default 44 is the budget.

  gap 1   defaults: grid 44 · swell 1 · T = 4.5% of the long edge
  gap 2   morph-count=52 · morph-spread=1.8 · morph-size=14

Ten matched pairs per gap (match keys m1–m10); scene 2 swaps the grid's rows,
so every pair also travels while it morphs:
  gap 1   ui3d→ui3d · ui3d→shape · shape→ui3d · iphone→ipad · ui3d→laptop ·
          chrome→ui3d · text→shape · shape→shape · text→text · shape→text
  gap 2   ui3d→iphone · shape→ui3d · ui3d→shape · ipad→ui3d · laptop→chrome ·
          ui3d→ui3d · shape→text · shape→ui3d · text→shape · text→ipad
Scene 1 carries the defaults (`morph=<mode>` only), scene 2 the tuned knobs —
a scene's `morph-*` params shape ITS way out.
