/* ============================================================
   Call2Learn — Notes & Print Portal
   Design language: a phone call becomes a paper record. The visual
   anchor is a "call receipt" — a perforated ticket stub, dot-matrix
   texture, timestamped like a printout — because that is literally
   what this screen produces. Dark indigo (the call/night-time end of
   the product) meets a warm marigold accent (the paper/print end).
