/*
 * /ffw/ — presentación del Método del Último Operador.
 *
 * Dos reglas gobiernan todo lo que sigue.
 *
 * 1. Proporción. Las medidas salen de φ (1,618) y de Fibonacci: los tiempos son
 *    89 / 144 / 233 / 377 / 610 / 987 ms, las columnas se parten 61,8 / 38,2 y
 *    los viewBox de las escenas usan lados de la serie. Nada de números al azar.
 * 2. Una idea a la vez. El contenido no aparece de golpe: cada `data-step` es una
 *    pulsación del presentador. Los elementos ocultos conservan su caja, así que
 *    revelar nunca reacomoda la slide.
