PartyRiff — design handoff (master brief, 5 Sep 2026)

Kept: purple/pink identity, avatars (your 89 looks in four packs), classic game names, central prompt, FX vocabulary, room settings, host-covers-room idea.

Changed: shared stage + phones is first-class (Connected, Alibi); quick start = group size · device · heat, Party Mix recommended first; unlimited neutral Pass; one heat vocabulary (Chill / Spicy / Wild / After Dark) with per-card ratings; result-specific moments with a signature gate; three identities (guest / member / paying host) and Friends; commerce as three annotated alternatives (monthly / packs / 48h pass); All-looks avatar default; text-field notches match containers; disabled primary CTAs replaced by readable dim + inline validation.

Removed: fake social proof, Chaos Dice, skip counters and "chickening out" copy, drink-based rankings and "room energy", credits, overlapping Plus/Pro plans, full-screen flash, victory FX on navigation, side-panel Imposter topic, harmful dares.

Deferred (P2): Story/Sketch Relay, Bluff Lab, Group Chat Court, Who Said It, photo games, Club Emergency, shared TV display, further locales, native shells, subscriptions beyond the annotated variant.

Metadata: { family, heat 1–4, topics[disclosure|dating|roast|performance|media], players, device, locale:en }. Every card is rated on its own; the category name never decides suitability.

Rules: read aloud before shipping; no ex-texting filler, gender/relationship assumptions, humiliating refusal, outsider contact, posting from another account. Every card needs an equally polished lower-exposure alternative. States per card: Favorite, Pass (neutral, unlimited), Report (reason chips, hides for this party), seen / skipped / reported tracked per deck cycle; exhaustion → explicit reshuffle only. Custom cards private to the party with preview / edit / delete / test.

Level 0 response 80–180ms · 1 result 200–500ms · 2 highlight 0.8–1.5s · 3 signature 1.5–2.5s. Triggers: Same Brain (≥4, all submitted, 0 passes/away, identical), Plot Twist / Caught (resolved Imposter outcome; split → "Imposter escapes"), Crown Steal (new sole leader after completed scored round; not first score), On a Roll (3 consecutive correct predictions, disclosed), Pulse Rush ready (3 distinct completed sets), Night Finale (completion or End). One signature per set, ~60s spacing else badge; cancel on context change; no leaks; fairness outside animation; shake 2–4px/120–180ms on decorative frames only; no strobe; hard mute; reduced motion = equal composition.

Guest refresh (same seat by id) · wrong/expired code · locked room · duplicate/long name · late join (spectator this round) · missing input (announced timeout/abstain) · disconnected (away, not a vote) · host loss (pause, host return default) · double tap (one award) · stale event after round change (ignored) · role on resume (own only) · heat change at safe boundary · no compatible cards (explicit) · exhausted deck (reshuffle) · insufficient players/devices (compatible alternative) · player leaves (per-game rule) · checkout cancelled/pending (return to party) · share cancelled · End (resolve then recap).

Timings (30/45/60s), counts (4–8 vs 9–12), prices and model, whether WYR needs any scoring, repeated exposure to signatures, reduced-motion parity, Quick start median (target ~30s; public copy "Start in moments").
