/* Blog bundle stylesheet. Dark-only, self-contained: the static pages are
   served outside the SPA, so the --bt-* values are inlined here rather than
   imported from shell-theme.css.

   Adopted from the M55 reference bundle, which produced the initial
   zero-article deploy before a content exporter existed. Per the Blog Content
   Delivery Contract, everything under site/ is content-side, so this file is
   now maintained here and shipped fingerprinted into site/assets/.

   Additions beyond the M55 reference are marked BOGA-CONTENT below. */
