/* ═══════════════════════════════════════════════════════════════════════════
   Blog theme — the static half of the site.
   ═══════════════════════════════════════════════════════════════════════════

   The 322 posts under blog-content/ are plain HTML served by Caddy; they never
   touch the React bundle, so client/src/styles/theme.css cannot reach them.
   They were written by a content agent against a generic slate-and-indigo
   palette: white page, #4338ca links, #f8fafc callouts, a #111827 CTA slab
   with an #f59e0b button. The blog INDEX had the opposite problem — hardcoded
   dark, with the violet #7c3aed we retired everywhere else.

   So: someone on light mode leaves a cream site and lands on a white page with
   indigo links; someone on dark mode gets flashbanged.

   This file is the blog's copy of the theme. The token VALUES are lifted
   verbatim from client/src/styles/theme.css — if that file's palette changes,
   this one has to change with it. It is duplicated rather than imported
   because the React CSS is bundled with a content hash and has no stable URL.

   The token names here are roles, not values (--blog-ink, --blog-card), unlike
   theme.css's generated --t-xxxxxx names. Nothing generated this file, so
   there is no dark-value invariant to preserve; these were chosen by hand to
   match what the site already looks like.
