/* ======================================================================
   SIC — iA Presenter Theme (v2 pass)
   Author: Scarlet Dame + GPT-5 Pro
   Notes:
   - Aligns with SIC Identity guide (colors, type, gradients)
   - Keeps iA's responsive layouts intact; only adjusts cosmetics
   - Safe to drop in alongside the default iA theme CSS
