/* ============================================================
   Artificial Consciousness Initiative — shared stylesheet
   Every page links this file; edit here once, not per page.

   Principles
   - One typeface (ET Book, Edward Tufte's Bembo revival) for everything,
     nav and captions included.
   - Hierarchy from size and italics, not from weight, caps, or colour.
   - Warm paper, near-black ink, one accent used sparingly.
   - A reading column on the left, a margin column on the right for
     notes, captions, and key facts — like the page of a book.
