/* ==========================================================================
   MappedBible — unified navigation system
   Built 2026-07-28. One stylesheet, three presentations:
     1a  grouped masthead + mega-menus   (all pages, desktop)
     1b  persistent study sidebar        (study surfaces only)
     1c  intent doors + bottom bar       (homepage hero / all pages, mobile)

   WHY THIS FILE EXISTS: the site is 14 hand-maintained static HTML files
   with no build step. Nav was duplicated in every one, and WEB_BUILD_LOG
   records repeated drift ("nav blocks must be kept identical manually").
   Nav markup now lives in nav.js and styling lives here — change once.

/* ==========================================================================
   DEFENSIVE RESETS — added 2026-07-28 after conflict audit.

   The 14 hand-maintained pages still carry their original inline <style>
   blocks, including bare element rules like:
       nav { display:flex; justify-content:center; gap:22px; margin-top:10px; }
       nav a { color:#6E6555; }
   Those were written for the old nav and are now orphaned, but they still
   match — .mb-bottom IS a <nav>, and .mb-drawer contains <a> elements.

   Class selectors beat bare element selectors on specificity, so anything
   this file declares explicitly already wins. The danger is properties this
   file does NOT declare (gap, margin, justify-content) silently inheriting
   from the legacy rule. These resets close that gap.

   The orphaned inline CSS should be stripped in a follow-up pass — it is
   dead weight and a trap for the next session. Doing it here, unverified,
   right before a deploy, is how a site breaks at 8pm.
