/* ============================================================
   Element reference pages + the periodic table.

   The old pages carried their own complete design — Archivo /
   Inter / IBM Plex Mono on #FAFAF8, blueprint #1B4965 and brass
   #A8763A. None of it survives. What survives is the CONTENT,
   re-dressed in this site's tokens.

   The one thing carried across visually is the amber accent's
   ROLE: on the old pages brass marked the element itself, and
   here amber does the same, which keeps the tiles reading as
   material rather than as navigation.
