The hero routes one request down one of three lanes (write, decide, act), weighed on quality, latency, cost and policy; Decide is Kai, drawn dashed and marked in progress. Under it: one runtime for every layer, the paths, the balance, the presets, one request end to end, the glue it replaces, models from the catalog's labs, agents, decisions, the measurement with the paper caveat, frontier standing computed from the board (on and off), infrastructure, the call, enterprise. Viewport rises and a magnetic start control, both still under reduced motion and touch. Gate: e2e/gates/enso.spec.ts. Co-authored-by: Hanzo Dev <[email protected]>

/**
|
|
* Magnetic — the loud control leans toward the pointer.
|
|
*
|
|
* A small pull, a spring back: the control follows the pointer by a fraction of
|
|
* the distance, capped, and grows a hair. It is the one control on a screen
|
|
* that does this, so the eye finds it without a glow.
|
|
*
|
|
* Only for a fine pointer with motion allowed. A touch, a coarse pointer or
|
|
* `prefers-reduced-motion` gets the control exactly as it is: nothing is
|
|
* attached, so there is nothing to undo. Transform only, so it never moves
|
|
* layout and composes with the control's own hover.
