/**
 * post-page.css — shared styles for blog post pages
 * Used by: all HTML files with <meta name="post_article" content="true">
 * Do NOT inline these in each page — they belong here.
 *
 * What stays inline in the HTML (per post-optimizer contract):
 *   - .article-content img { ... }   (Step 11 check #8 literally greps HTML)
 *   - .toc-nav / .toc-list ... (Step 11 checks #14 literally grep HTML)
 *   - .blog-hero background-image url(...)  (per-article)
 *
 * Placeholders filled at install time by /init-blog-framework:
 *   #1F2937        — primary brand color (hex), e.g. "#1F2937"
 *   #374151   — lighter variant for gradient stop, e.g. "#374151"
 *   #DC2626       — CTA button color (hex), e.g. "#DC2626"
 *   #B91C1C — accent button hover, e.g. "#B91C1C"
