   COMPONENT: hub (pillar / hub pages — Soft Glass direction)
   Used by template-hub.php on the founder-finance / FIRE / build pillar pages.
   All selectors are scoped under .bc-hub so this never leaks into the rest of
   the site (auto-enqueued site-wide via the components glob). Consumes the DS
   tokens (design-tokens.css) so it adapts to light/dark; adds Sora for display.
