/* ============================================================
   App Notes — section stylesheet
   p1next.com/app-notes/  ·  created 2026-08-03 (Day 46)

   Scope: the App Notes article section ONLY. Loaded after
   css/styles.css and never instead of it — every base token
   (--navy, --gold, --midnight, …) comes from styles.css :root.

   This file exists so a new article is a copy-paste of an
   existing one rather than a redesign. Do not inline these
   rules into a page; extend them here.
   See _research/blog-pattern.md for the authoring contract.

   the slot's BACKGROUND and the <img> sits on top of it. If the
   asset 404s, anLogoFail() removes the <img> and the monogram
   is simply revealed — there is never a broken-image icon and
   the slot never collapses. Set colour with --c, letters with
   data-mono. The <img> is decorative (alt="") because the tool
   name is always present in adjacent real text.
