PDP-03 — Below-The-Fold (BTF)
Build all below-the-fold PDP sections: sequence active sections from strategy, write copy for each, embed in HTML component templates. Covers product highlights, UGC, expert, ingredients, timeline, problem/solution, comparison, cost savings, reviews, FAQ, guarantee, and all other BTF section types. Each section is self-contained (hunt-and-peck) with proof, design notes, and mobile behavior.
