1// ChirpPairingFlow — the audio pairing screen.2//3// Implements the three-act bird animation specified in the brief §6.2:4//   Act 1 (Waiting) — desktop bird idles, soft pulsing chirp ring5//   Act 2 (Contact)  — mobile bird hops in, sound-wave arcs in both6//                       directions, head-tilt reaction7//   Act 3 (Paired)   — sound waves resolve into a glowing connection dot,8//                       both birds wing-flutter, copy switches to "Paired!"9//10// The acts are bound to the `PairingPhase` enum from sync-types; the11// background coordinator drives the phase forward as the audio + Noise12// rounds make progress. The component stays a pure renderer: it does not13// touch the microphone or the WebSocket itself.1415import { Component, Show, createEffect, createSignal } from "solid-js";16import type { PairingProgress } from "../../shared/sync-types";1718export interface ChirpPairingFlowProps {19  progress: PairingProgress;20  /** Called when the user taps Retry on a terminal-error state. */21  onRetry: () => void;22  /** Called when the user taps Cancel/back on the idle/listening state. */23  onCancel: () => void;24  /** Called once the paired-state dismissal animation completes. */25  onDismiss: () => void;26}2728const PAIRED_DISMISS_MS = 2500;2930export const ChirpPairingFlow: Component<ChirpPairingFlowProps> = (props) => {31  const [dismissArmed, setDismissArmed] = createSignal(false);3233  createEffect(() => {34    if (props.progress.phase === "paired" && !dismissArmed()) {35      setDismissArmed(true);36      const t = setTimeout(() => props.onDismiss(), PAIRED_DISMISS_MS);37      // No need to clean up on unmount — onDismiss is a no-op if parent unmounted.38      void t;39    }40  });4142  return (43    <div class="peach-chirp-pair" data-phase={props.progress.phase}44         onClick={() => props.progress.phase === "paired" && props.onDismiss()}>45      <div class="peach-chirp-stage">46        <DesktopBird phase={props.progress.phase} />47        <SoundWaves phase={props.progress.phase} />48        <MobileBird phase={props.progress.phase} />49        <ConnectionDot phase={props.progress.phase} />50      </div>5152      <PairingCopy progress={props.progress} />5354      <Show when={canCancel(props.progress.phase)}>55        <button class="peach-btn peach-btn-ghost peach-chirp-cancel" onClick={() => props.onCancel()}>56          Cancel57        </button>58      </Show>59      <Show when={isTerminalError(props.progress.phase)}>60        <button class="peach-btn peach-btn-primary peach-chirp-retry" onClick={() => props.onRetry()}>61          Try again62        </button>63      </Show>64      <Show when={props.progress.phase === "mic_denied"}>65        <p class="peach-chirp-mic-help">66          Update your browser's site settings to allow Peach to access the microphone, then try again.67        </p>68      </Show>69    </div>70  );71};7273function canCancel(phase: PairingProgress["phase"]): boolean {74  return phase === "listening" || phase === "chirping" || phase === "handshake";75}7677function isTerminalError(phase: PairingProgress["phase"]): boolean {78  return (79    phase === "timeout" ||80    phase === "handshake_failed" ||81    phase === "version_mismatch" ||82    phase === "mic_denied"83  );84}8586const PairingCopy: Component<{ progress: PairingProgress }> = (props) => {87  return (88    <div class="peach-chirp-copy">89      <h2 class="peach-chirp-headline">{headline(props.progress)}</h2>90      <p class="peach-chirp-sub">{subtext(props.progress)}</p>91    </div>92  );93};9495function headline(p: PairingProgress): string {96  switch (p.phase) {97    case "idle":98    case "listening":99    case "chirping":100      return "Hold your phone near your laptop";101    case "handshake":102      return "Pairing…";103    case "paired":104      return "Paired!";105    case "timeout":106      return "Couldn’t find your phone";107    case "mic_denied":108      return "Microphone access needed";109    case "version_mismatch":110      return "Update Peach on both devices";111    case "handshake_failed":112      return "Something went wrong";113  }114}115116function subtext(p: PairingProgress): string {117  switch (p.phase) {118    case "idle":119    case "listening":120    case "chirping":121      return "Peach will pair automatically when your phone is close";122    case "handshake":123      return "Hold still — exchanging keys";124    case "paired":125      return p.peerDeviceName ? `Connected to ${p.peerDeviceName}` : "Connected";126    case "timeout":127      return "Make sure Peach is open on your phone and try again";128    case "mic_denied":129      return "Peach uses your microphone to pair.
