   EDITORIAL LIBRARY

   The premise: this is a study product, so it should feel like a
   well-made book — not a crypto dashboard. Every rule below exists
   to keep it on the right side of that line.

   1. WARM, NOT COLD. The base is warm ink (#0D0C0B), never blue-
      black. Warmth reads human; blue-black reads generic tech.
   2. PAPER BREAKS. Cream sections interrupt the dark. The contrast
      does the work that gradients and glows were doing badly.
   3. ACCENT IS PUNCTUATION. Brass appears on well under 5% of the
      page. If it were everywhere it would mean nothing.
   4. NO AMBIENT DECORATION. No glows, no aurora, no particles, no
      floating shapes, no glass. Hierarchy comes from type, space
      and hairlines.
   5. TYPE PAIRING. High-contrast serif for display, Inter for
      everything you actually read.
