/* ── Horizontal overflow / iOS scroll containment ─────────────────────────
   Problem: on iOS Safari, position:fixed elements are NOT clipped by an
   ancestor's overflow:hidden. The Bootstrap offcanvas-end uses
   transform:translateX(100%) when closed, which places it entirely
   off-screen to the right. iOS then treats the page as scrollable from
   0→2×viewport-width, letting the user "scroll right" to see nothing.

   Fix strategy (layered):
   1. overflow-x + overscroll-behavior-x on html & body — handles non-fixed overflow.
   2. max-width:100vw — hard caps the document width to the viewport.
   3. Offcanvas-specific override below (fade instead of slide) — removes the
      translateX(100%) that extends the fixed element off-screen.

/* ── Offcanvas: swap slide-from-right for fade on mobile ───────────────────
   Bootstrap's .offcanvas-end uses transform:translateX(100%) in its closed
   state. Since the offcanvas is position:fixed, iOS Safari counts that
   off-screen transform position when computing the scrollable page width,
   making the page appear to have content 390px to the right.
   Replacing with opacity-based fade removes the off-screen transform entirely.
   Bootstrap's transitionend listener fires on the opacity transition, so
   class management (showing / show / hiding) continues to work correctly.
