Context Halo

reveal nearby relevant context around a focused element

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

"Context Halo" — reveal nearby relevant context around a focused element. It has a gravity layer (universal attraction toward mass), a memory layer (a decaying trail / hysteresis), a link layer (ropes / cloth between neighbours), and a cohesion layer (flocking — pull toward neighbours). The active render stack is metaballs, links, particles.

A focused element becomes a gravity well that draws nearby definitions, examples, and prior interactions inward — relevance ranked by relation strength, not fixed placement.

Render: metaballs · links · particles
Reduced motion: a context panel with a related-links list and local callouts
Without motion: related context reads as a panel of ordered related links and callouts ranked by relation strength
