/* ─────────────────────────────────────────────────────────────────
   /education/ — education-vertical site overlay.
   Inherits from ../assets/styles.css. Sage-green accent (#2F6F4F)
   chosen for the academic-growth-calm associations of green/blue
   without competing with healthcare's teal, seceng's neon green,
   or government's red. Brand orange retained on the primary
   "Schedule a working session" CTA so cross-vertical CTA muscle
   memory holds.
