Audit 1.7/2.5 (t4 lines 66-68, 120-122): the prototype draws 30 discrete bottom-anchored bars (radius 2, vertical gradient); the build's VisualizadorAudio painted a single continuous oscilloscope stroke, so its `barras: 30` parameter never produced bars. Adds an opt-in `barrasDiscretas` mode (default false, byte-identical continuous rendering preserved for any other caller) plus a `gradienteFinAlpha` knob for the two screens' differing gradient end-alpha (.3 vs .45). Wires it into the Escuchar hero and the full player, correcting the player's bar count/height to match the prototype (26->30 bars, 46->40px) at the same time.
