/* ============================================================
   ARECH News List block — front-end styles.

   Port of the LIGHT body of the prototype
     prototypes/news-list-v1/index.html
   (the .filter-section + .grid-section regions ONLY — the navbar / breadcrumb /
   dark editorial header / footer are separate global blocks and are NOT styled
   here). Re-tokenized to the theme tokens (main.css :root) and corrected to the
   responsive standard (responsive_manual_en_0.1: min-width ONLY, no max-width
   media queries; canonical container box --container 1140/1200).

   ALL rules are scoped under `.arech-news` so nothing leaks into the theme.
   Font families use theme tokens (--font-mono / --font-headline / --font-body)
   so a later phase can remap them globally — no literal family names.
