   series-shell.css — shared "Series Shell" for series.html and
   source-series.html (see series-layout-suggestion.md).

   One skeleton, two content modes. Loaded AFTER main.css so it
   supersedes the old hero styling on these two pages only; no
   other page references .series-shell, so nothing else moves.

   Spacing scale: 4 / 8 / 12 / 16 / 24 / 32 / 48px only.
