Concept Cluster

group related terms, cards, or sections without hard layout changes

Running the actual pattern live via applyPattern() — switch the substrate, stack overlays, watch the signals, or reverse the dynamics. Not a mock.

"Concept Cluster" — group related terms, cards, or sections without hard layout changes. It has a cohesion layer (flocking — pull toward neighbours), a crystallize layer (snap matter onto a lattice), a link layer (ropes / cloth between neighbours), and a memory layer (a decaying trail / hysteresis). The active render stack is metaballs, links, particles.

Related concepts cluster without a rigid layout (cohesion + crystallize); active concepts strengthen nearby terms; unrelated ones cool and drift.

Render: metaballs · links · particles
Reduced motion: concepts collapse into grouped lists; active groups keep emphasis
Without motion: related concepts are grouped under headings with relation badges
