/* ==========================================================================
   Blog — index, archives, search.

   Structure is the Kissflow blog's (kissflow.com/blog, measured 2026-09-11):
   centred title band → spotlight post beside a side tile and a subscribe box
   → "All blogs" three-up grid with a promo tile in the fourth slot → View more
   → Meet the authors. Everything visual is this theme's: the contact page's
   pattern band, the 1264 measure and 32px gutters of section 05, hairlines in
   --gw-line, images on an 8px radius, Cal Sans / Space Grotesk / Inter on the
   ramp in tokens.css. Kissflow's cards are borderless with a bordered image;
   that is kept — the image carries the hairline, the card does not.
