/* MNEOS site rebalance — 2026-07-29
 *
 * Adds the four-bucket nav, expanded footer, Learn hub, Current Build Status
 * panel, and simplified homepage hero introduced by the 2026-07-29 morning
 * directive from David Sherrer.
 *
 * Design tokens follow the existing homepage.css conventions:
 *   accent color derived from --r-accent (falls back to a professional teal)
 *   type stack derived from body font-family
 *   spacing scale uses rem units multiples of 0.25rem
