 * B-v2 Industrial Premium — shared chrome.
 *
 * Nav, Footer, PageHero, FinalCta, button primitives. One stylesheet
 * sourced by every redesign page; markup lives in each page's HTML.
 *
 * Class names are namespaced with `b-` so they don't collide with the
 * legacy landing-*.css and portal-*.css that still ship alongside.
 *
 * Ported from Designs/dev-handoff/components/shared.jsx (the bShared
 * inline-style object) — see docs/research/design-handoff-fit-analysis.md
