/* ============================================================
   KEEP ME POSTED — mailing-list sign-up
   One source for the footer strip (stamped into every page via
   footer-tagline.html) and the fuller subscribe.html panel.
   Posts straight to Buttondown; no JavaScript anywhere.
   The footer sits on two grounds — night everywhere, vellum on
   .article-page — so every colour below has a light-register twin.
   ============================================================ */

/* The footer is stamped into every page, and the site has two footer grounds:
   night (most pages) and parchment (.article-page vellum, .home-codex,
   .cal-page). Everything below reads three tokens, so adding a new register
   later means adding one selector here and nothing else. */
