/* The Bloomsbury Society — the /posts/ pages.

   Replaces _base's theme.css, whose rules draw Brain and Behaviour's parts: none of them
   is used here. Every value below is the kit's (design drop design.2026.09.17-1,
   ui_kits/website/Shared.jsx and components/) as the site repo's src/components/ port it,
   so a page here and a page of the site are the same design. The site sets these values
   inline, as the kit does; here they are classes, because a template is easier to read
   without them and a class can carry its own hover.

   The kit has no media queries — it was drawn at 1280x900 — so the responsive rules at
   the foot are the site's additions (its src/styles/static-hover.css), not ports. */
