/* Blog-only structural styles.
 *
 * Measure, type scale, link treatment, `.table-scroll`, `.display` and `.lede`
 * come from site.css (Concept C). This file holds only what is blog-specific:
 * the editorial list, provenance grid, optional cover, inline CTA and related
 * list. Only what is genuinely blog-specific lives here.
 *
 * External on purpose. cp-web serves an ENFORCING CSP whose style-src is
 * "'self' 'nonce-<per-request>'" (apps/_shared/middleware.py), so an inline
 * <style> without a nonce is dropped silently: the page still returns 200 and
 * still paints, and only the behaviour disappears. A stylesheet served from
 * the same origin needs no nonce and cannot fail that way.
