/* ===========================================================================
   SILVER PRINT — Mobile layer  (linked with media="(max-width: 900px)")
   ---------------------------------------------------------------------------
   Complete replacement for assets/css/mobile-redesign.css, which is NOT
   loaded for this skin (manifest: "legacy_mobile_layer": false). Because that
   layer is gone, this file must also re-assert everything assets/css/style.css
   does inside its own max-width 900px block — otherwise the old dropdown
   panel nav comes back.

   900px is the single mobile cutoff and matches, exactly:
     - the media attribute the manifest declares
     - matchMedia('(max-width: 900px)') in assets/js/mobile-redesign.js:15
   CSS and behaviour therefore cannot disagree about what "mobile" means.

   assets/js/mobile-redesign.js is untouched, and it runs whatever the
   manifest says — the flag governs the stylesheet, not the script. This file
   styles the DOM that script injects:
     .mr-drawer-head with .mr-drawer-brand and .mr-drawer-close,
     .mr-backdrop, menu-open on BOTH html and body,
     mr-has-drawer-head on html,
     .mr-bottomnav with .mr-bn-item, .mr-bn-icon, .mr-bn-label, .is-active,
     and .gallery-tile.is-loaded.
   Leaving any of those unstyled is the failure mode this file exists to
   prevent; a bottom navigation bar with no rules is not invisible, it is a
   pile of unstyled links at the end of the page.

   TWO of the skin's three forced declarations live here, in section 1 and
   section 6. Each cancels an existing forced declaration and says so.
