 * brand-intro.css — Signature brand intro.
 * Concept: the "PIA Industries" wordmark is the GROUND / ROOTS. The white pine
 * tree grows up out of it, surges to full strength, the base anchors with a firm
 * thud, then the tree withstands a buffeting shake (rooted = indestructible).
 * Self-contained: all selectors prefixed .brand-intro-*. Never leaks into the host.
