   Palette:  Deep blue #123C69 (nav/footer/authority), Blue #1D5FA8
             (links/CTAs), Blue-soft #EAF2FB (section tint), Warm
             white #FAFBFD, Berry pink #C13C6B (accent only — never
             a background fill), Pink-soft #FBEAF1, Ink #10233F,
             Slate #5B6B85 (secondary text).
   Type:     Display -> 'Fraunces' (headlines, warm/characterful serif)
             Body    -> 'Manrope' (clean, modern, welcoming)
   Signature: the "ruler-tick" motif — alternating blue/pink ticks
              drawn from a school ruler/ledger sheet — used as section
              dividers and the active-nav-link underline.
