/* ============================================================
   FOOTER — Wynter structure, sitewide
   Wordmark top-left above four columns, then a bottom bar with social on the
   left and copyright plus legal on the right.

   This file is the footer's OWN stylesheet and the footer markup links it
   (scripts/build-footer.mjs emits the <link> inside the yp:footer block), so
   the rules travel with the markup to every page that carries the footer:
   the static pages, the five landing pages, and the server-rendered routes.
   It used to live in yieldpage.css, which the self-contained static pages
   (/contact, /message-market-fit, /ai-info, /privacy, /terms, /404) never
   load, and the footer shipped unstyled on all six. scripts/verify-footer.mjs
   asserts the link and this rule on every page after each build.
