S4 → S5 · SIGNATURE MOMENT · MOTION SPEC + LIVE DEMO

the crew changes,
and the room re-ranks.

your people are the input. add or drop someone and the recommendations resettle — a think, a flip, and the night's best table lands platinum. crew is a taste signal, never an invite.

LIVE · TAP TO RE-RANK

toggle who's out tonight. the list resettles around shared taste; per-head splits the table minimum across the crew.

YOUR CREW —

re-rank is interruptible — toggle again mid-flight and it restarts from the think beat, never queues. when fewer than two of your crew share taste, the list falls back to crowd reasons and no table takes the platinum.

MOTION TIMELINE · NORMATIVE

every re-rank runs this fixed choreography. total signature moment ~900ms; the platinum border always lands last.

CHIP COMMIT

the toggled chip commits with a light haptic and a scale settle.

THINK

cards dim to 70% under a shimmer sweep; the crew line echoes the input first, so the read feels considered.

FLIP RE-SORT

first / last / invert / play — cards travel to new positions. position only, no size morph. top three stagger.

WHY + PLATINUM

why-chips crossfade to their new reasons, then the platinum #1 border lands last on the top card.

INVARIANTS

interruptible: a new toggle restarts from T+80, never queues.
low-confidence (<2 taste-connected): no platinum #1, why-chips generalize to crowd reasons, flat rank weights — and we never say we're less sure.
reduced-motion: the whole moment collapses to a 200ms crossfade re-order.
movement ticks show ▲/▼ with the rank delta beside moved cards, ~1.7s, then fade.
