   FoodProTec — "clean industrial architecture" (content/design-notes/redesign-review.md, GPT v3, 2026-09-07).
   The one stylesheet for every served page: hub, 7 spokes, about, contact, calculator, intake.
   White + pale mineral grey surfaces, deep charcoal type, FoodProTec red for actions, a little icy blue.
   Hanken Grotesk everywhere (Barlow Condensed and Inter retired). Content column 1280px, 8–12px corners,
   fine neutral borders, one dark proof chapter + the footer. Calculator machinery (assets/calc.js) keeps
   its DOM contract; only the looks change here.
