*I'm a little vague on the form-factor distinctions here – for instance, if a "surface" is just a big sheet of inert Korean vinyl with some point-of-purchase QR codes printed on it, what's all "surfacey" about that?

Try to imagine one's self in a mid-century climate-crisis culvert, damp, hungry and homeless, ceaselessly fondling a busy interface that appears to be one grimy, five-cent sheet of 20-lb bond typewriter paper. Yup, that's all too plausible, but would any client pay you to forecast that? Heck no.
