The detector does not ask whether the frame is pretty. It asks whether the frame is doing the work the aesthetic actually does. A real Aero frame breathes, it has the softness of the gradient, the life of the organic element, and the restraint that keeps the glass looking like a surface and not a lens. A yams frame is the opposite, all the shine and none of the substance, the glaze stacked so thick the thing under it stops mattering.
The first tell is the organic element. The leaf, the water, the bubble, the plant pressing up through the corner, any of them reads as life, and a frame with none of it is already on the yams side no matter how clean the gradient runs. The second tell is the gloss ratio. A soft highlight that makes the panel read as glass is the point of the style, but a highlight cranked until it drowns the frame, the chrome ball sitting on top of the gradient, is the tell that the shine is doing all the work. The third tell is the contrast dial. Aero runs soft, the colors close together, the mood gentle, and the frame that pushes the saturation and the contrast until everything is neon is past the style into the yams lane.
That is the whole reason the split works as a game. The three tells are fast to read once you know them, the organic element or not, the gloss doing the work or not, the contrast cranked or not, and the detector turns the reads into a score. Six frames, two calls each, and the purity card the run earns. The certified glazer sees the shine and calls it Aero, the purist smells the glaze from the first frame, and the apprentice is the one who gets the obvious ones and slips on the subtle.
