/* REDESIGN 2026-10, v2 — the structure of a product site (after openrouter.ai): an app header
   with search, a centred hero with a row of numbers, a grid of feature cards, dense tabbed lists,
   and long-form text in a docs layout with a sticky index. The publication's own system stays:
   IBM Plex, the seven daily finishes and day/night from finish.css, and the accent (--stamp)
   used for measured figures and due dates, never for decoration. Pages opt in with
   <body class="rd">; the home page adds "rd-home". Issued documents never get it. */
