/* ============================================================
   SERIES HUB — shared layout for the six series index pages
   (Objects, Glass Cases, Portraits, Music, Food, Learning).
   Loads after codex-room.css: the room supplies the vellum ground and
   the opening band, this file supplies the series-specific browsing
   grid. Per-series identity is a single custom property, --room-pigment,
   set inline on each page - nothing else about the layout varies.
