coral

morph="coral" — bioluminescent coral overgrows the element and recedes off its partner (match-morph-coral.ts). ONE scene, in-scene `morph-to` links, no cuts.

Read the rig's notes

A reef crust spreads over the outgoing element from its silhouette's edges
inward — dark cellular coral, polyp cups glowing cyan / magenta, a hot growth
front spilling light onto the picture ahead of it — while ≈90 seeded coral
trees sprout on the contour (and inside, as the crust reaches them), fork a
few levels with glowing tips, and pop fuzzy polyp blooms. Fully covered at
the middle of the window, the picture underneath swaps to the incoming
element; then the coral withdraws back to the edges and vanishes, leaving
the incoming element clean. G = 0 at both ends: exact hand-offs.
