   Droplet FABs — Estetica gota de agua para VoiceLytiks + LytikBot
   ═══════════════════════════════════════════════════════════════

   DECISIONES DE DISENO:
   ─────────────────────
   Forma:    border-radius asimetrico → forma organica de gota
   Material: glassmorphism (backdrop-filter: blur + fondo semi-transparente)
   Click:    scale + morph → la gota "crece" como si absorbiese liquido
   Idle:     animacion sutil de flotacion → parece que flota en agua
   Hover:    brillo interior + escala ligera → respuesta tactil
   Grabando: pulsacion roja + onda expansiva → indica actividad

   Compatibilidad: backdrop-filter soportado en Chrome 76+, Safari 9+,
   Firefox 103+. Fallback: fondo solido semi-opaco.
