/* =============================================================================
   blog.css — shared layout for the Wildlife Alert blog (/blog and /blog/*)
   -----------------------------------------------------------------------------
   Loaded AFTER brand.css and site.css by blog.html and every blog-<slug>.html
   post. Kept in one shared file rather than duplicated into a page-local <style>
   block on each post, because every post uses the identical layout — a new
   article should be prose plus metadata, nothing else.

   Every color, type, spacing, radius, and shadow value references a brand.css
   custom property via var(--token). There is NOT ONE literal color value in this
   file, so it passes scripts/brand_lint.py.

   Widths are max-width / ch / % only — no fixed px width — so the pages reflow
   cleanly from 320px to 1920px.
