/* =====================================================================
   AGORA landing — Greek temple with four pillars.

   Architecture (top to bottom):
     pediment  →  entablature  →  columns (pillars)  →  stylobate
                                                       ↓
                                                     captions (museum-style)

   Two of the four pillars (Synthesis, Survey) are live anchors;
   the other two are disabled placeholders.
