ink

morph="ink" — ink into water (match-morph-ink.ts).

Read the rig's notes

One sheet, larger than the frame, samples both snapshots through a curl-noise
streamline trace whose length ramps up and back down: the outgoing element
bleeds into curling dye plumes — its coloured accents stay dense, its dark
bulk thins to a haze, billows carry thin wisps at their edges — the plumes
drift and mix, a noise front hands the dye over, and the incoming element's
dye condenses back into place (same field, reverse time). Exact at both ends.

ONE scene, no cuts — the in-scene `morph-to` links, so every mid frame can be
shot. The hero in the middle, 1.8 s per hand-off:

  1.6 → 3.4   stat card  → iphone        defaults (morph=ink)
  4.4 → 6.2   iphone     → music card    morph-spread=1.3 · morph-color=#1b6fa8 (water veil)
  7.2 → 9.0   music card → stat card     morph-spread=0.7 · morph-seed=11

Content is deliberately saturated (magenta / cyan / yellow) — the dye's colours
come from the picture itself, so a vivid picture makes vivid ink.

Camera never stops (linear kfs, r 760 about the origin): each hand-off swings
across the subject — −20°→+16°, +36°→−24°, −16°→+22° azimuth, 8% closer mid-window
(1 and 3 kept narrow: the ink sheet is baked through the start camera and jumps at the swap).
