/* ============================================================
   MASS TUTORING — DESIGN SYSTEM v3
   "A clean, academically credible SAT resource platform built
   around blue, white, black, and controlled neutral grays."
   ------------------------------------------------------------
   Typography: Sora (display) + Inter (body), self-hosted.
   Color rules:
   - One primary blue system: #1769AA (hover #12578F, active
     #0E4776). All CTAs, links, active states share it.
   - Blue guides attention; white creates clarity; near-black
     (#101820 / #0D1721) provides structure; gray supports
     hierarchy. Green/amber/red appear ONLY as status colors.
   - Key contrast results (WCAG 2.2 AA) are recorded in
     docs/COLOR-REDESIGN.md.
