+% Cover page — a hand-drawn "agent motif": a central AI core with radiating
+% arms ending in tool glyphs (the "one agent + many tools" idea). Pure vector
+% TikZ, navy line art on white — no external image, fully reproducible. The
+% build date is stamped near the bottom so successive versions are distinguishable.
