/*
 * blog-post.css — shared styles for individual blog post pages.
 * Linked AFTER ../styles.css so these post-page rules (e.g. .tag, .blog-post-meta)
 * override the index-card versions defined in styles.css, exactly as the former
 * inline <style> blocks did. Only linked on post pages, so the index is unaffected.
 * Theme-aware: colors use the CSS variables from styles.css (light + dark).
