   Overrides on top of /assets/css/clay.css (v27 "Warm Bronze Clay").
   Load order: clay.css FIRST, then this file. Everything here reuses clay's
   tokens (--ink*, --bronze*, --line, --clay-*, --r*, --ease, --gutter) and
   only adds what the blog needs: the mobile sticky bar, category pills,
   post-list meta, pagination, the subscribe band, long-form article type,
   the author block and the admin login card.
   The /manage/ screens do NOT use this file — see admin.css.
