   Unified navigation (same hamburger + drawer on every screen size),
   fixed bottom navigation, install app UI (button, iOS popup, footer cards).

   1) UNIFIED NAVIGATION (RE-ENABLED, this time without the overlap bug)
   HISTORY: this file previously force-hid .header-upper/.nav-outer/
   .right-column and force-showed .mobile-custom-header at every screen
   size via !important with no breakpoint condition, while header.php's
   own inline styles showed .header-upper at 768px+ via Bootstrap's
   d-none/d-md-block — two rulesets fighting each other, so on wide
   viewports both headers ended up visible at once. That's fixed now at
   the source: header.php's .header-upper div carries only "d-none" (no
   "d-md-block"), so it's hidden at every width, and .mobile-custom-header
   is shown unconditionally below — only one header can ever be on
   screen, on mobile or desktop alike.
