/* ICTRA research edition, 18 October 2026.
   THESIS: a readable research publication with image-led opening spreads.
   WORLD: white paper, navy type, teal wayfinding, Literata and Public Sans.
   PATH: overview, question, method, engineering, evidence, responsibilities.
   FIRST VIEW: one-line navigation; a clear title beside an image or introduction.
   INTERACTION: persistent section index, native disclosures, shared-time waves.
   Existing research, imagery and provenance remain the source of truth. */
