   The founder: "everything on the side panel, upper section links, are pretty

   The diagnosis: it was tasteful, and it was a normal website panel. It had no
   relationship to the world behind it. Everything below borrows the world's own
   physics rather than inventing a second visual language:
     - one light source, upper left, exactly like the moon in the scene
     - gold that behaves like LAMPLIGHT, pooling on hover, never a flat colour swap
     - headings CARVED, the way the Stoa's inscriptions are cut, not just set
     - the panel composes itself on open instead of arriving as a finished slab   */
