/*
 * PLAYA RESERVAS — ROI Calculator widget (v1.0.8)
 * ─────────────────────────────────────────────────────────────────
 * Sprint v1.0.8 P0.4 — Calculadora de retorno de inversión en landing.
 *
 * Closes la objeción "€49/mes es caro" del Cliente_Piloto_Playbook.md
 * convirtiendo el playbook script "1 reserva al mes te paga la
 * herramienta" en input interactivo. Visualiza pérdida anual estimada
 * por no responder al teléfono vs coste anual del plan.
 *
 * Convención: prefijo `roi-calc-*` para no chocar con `lp-*` (landing)
 * ni con clases Bootstrap. Reusable en landing, signup, admin.
 *
 * Mobile-first: <640px columna única. Desktop: grid 2 columnas.
 * Sin Bootstrap. Sin dependencias. Print-friendly (display:none).
