/* porras.dev — copper & verdigris on cold iron. Grotesque display, sans body.

   Copper and verdigris are the same metal at two ages: systems that endure.
   Claude came up with that metaphor and has been unbearably smug about it
   ever since. Porras approved the palette; the smugness was non-negotiable.
   v2: same metal, colder forge. The parchment went; the metaphor stayed. */
