/* Blog pages.
 *
 * The landing page keeps its marketing chrome in an inline <style> block, so
 * the header and footer rules it needs are repeated here rather than shared.
 * Only the handful the blog shell actually uses — copying the whole marketing
 * stylesheet would guarantee the two drift apart.
 *
 * Colour and spacing come from styles.css, which already aliases --ink-* onto
 * --text-*, so both files stay on the one palette. */
