/**
 * Voice-to-PR — phone-first feature dictation.
 *
 *   GET  /voice            → polished hero + tap-to-talk + repo picker
 *   POST /voice/transcribe → JSON, runs interpretVoiceTranscript
 *   POST /voice/ship       → ships a `.gluecron/specs/voice-*.md` ready spec
 *   POST /voice/issue      → opens an issue via the existing flow
 *
 * Hard rules (per the build prompt):
 *   - No shared layout / component changes (one nav link is added in
 *     `layout.tsx`, separately).
 *   - Inline JS lives here, in a single `<script>` tag.
 *   - Every CSS class is prefixed `.voice-*`.
 *   - Web Speech API is feature-detected — if unsupported the UI falls
 *     back to a plain textarea so the demo still works in Firefox / dev.
 *   - Skips gracefully when ANTHROPIC_API_KEY is unset (Claude call
 *     returns a heuristic interpretation instead of a structured one).
