/* -- Mobile Nav Panel (lives OUTSIDE header in DOM) ----------- */
/*
 * FIXED 2026-08-08. Aaron reported the open drawer had its top items hidden and
 * its bottom items unreachable, with no way to scroll to either. Measured in a
 * real headless Chrome at a 360px-wide phone with an 800px LAYOUT viewport but
 * only ~610px actually VISIBLE (browser URL bar + system nav bar cover the rest).
 * Two separate, independent faults -- both reproduced, both fixed here:
 *
 * FAULT 1 -- THE TOP WAS COVERED, NOT MISSING.
 *   .utility-bar and .ticker both carry z-index: 1100. The panel was 1051.
 *   So the black bar and the orange ADU-Home-Tour ticker painted OVER the open
 *   drawer, swallowing the first nav item AND the close button. Measured proof:
 *   elementFromPoint at the close button returned A.ticker__link, and the close
 *   button tested reachable: false. That is why nothing up top was clickable.
 *   FIX: panel z-index 1101 (above 1100), overlay 1100.
 *
 * FAULT 2 -- height: 100vh LIED, so the bottom could not be scrolled to.
 *   100vh resolves to the LAYOUT viewport (800px), not the visible area (610px).
 *   The panel therefore believed it was 800px tall with only 836px of content,
 *   giving just 36px of available scroll -- while 226px of scrolling was needed
 *   to bring the last item into view. Measured SCROLL_SHORTFALL: 190px, leaving
 *   'LET'S TALK' and the phone number permanently unreachable. This is the exact
 *   chronic bug documented in skills/mobile-nav-scroll/SKILL.md.
 *   FIX: 100dvh (dynamic viewport height) with the 100vh line kept ABOVE it as a
 *   fallback for old browsers, plus generous bottom padding so the last item
 *   clears the address bar instead of sitting flush against it.
 *
 * Do NOT reintroduce `right: -100%` for the slide -- it can cause horizontal
 * page scroll. transform: translateX() never does.
