 * blog.css — Blog index (home.php) + archives (archive.php)
 *
 * Source of truth: gibson-blog-archive-toggle.html (Daedalus, approved v2).
 * Only this template's UNIQUE selectors live here. Design tokens, nav, footer,
 * global map, popup, mobile phone bar, .cta-btn, and .container all come from
 * global.css — never redefined here.
 *
 * NOTE for centralization: the source defined light/dark CONTENT-TEXT tokens
 * (--body-text*, --muted/softer/faint-text, --border-soft*, --surface-card) and
 * the bottom .cta section chrome inside its page <style>. global.css does not
 * yet carry them. They are scoped here so the blog template renders faithfully;
 * if/when another template needs the same tokens or the .cta section, promote
 * these blocks to global.css to keep a single source of truth.
