PLATE 1B · EDITORIAL: ONE STREET, FOUR WEATHERS PEN & INK

Editorial cartoon: One Street, Four Weathers

Same storm, four forecasts: the hurricane only hits the shop that sold its doorway traffic. The bar that owns its regulars got a sunnier terrace out of the same weather system — and the department store is just moving the tills.

PLATE 3C · EDITORIAL: OLD VS. NEW MARKETING FLOW PEN & INK

Editorial cartoon contrasting Old Way human attention tricks with New Way agent information filter

Human attention tricks bounce off the shield; fast filters + verified specs flow through. A human shopper (bandwidth: 3 items) gets hijacked by celebrity smiles and emotional hype; a personal agent (100× bandwidth) blocks hype, uses Brand Trust & B2A Ad Bids as a fast Stage-1 filter, and audits JSON-LD specs to order the $89 winner.
