/* ============================================================
   Melanie Black — design system
   Chalkboard palette (deep chalkboard green, chalk white/yellow/pink)
   paired with Signal's clean type system (Manrope headlines, Inter body).
   Concept: a working binder/syllabus, staged like notes pinned to a
   chalkboard — paper cards for content, chalk tones for structure.
