   Findex News Runtime Pro — NATIVE MOBILE APP LAYER
   File: assets/fnrp-mobile-app.css   (pairs with assets/fnrp-mobile-app.js)
   ─────────────────────────────────────────────────────────────────────────────
   WHAT THIS IS
   A true app-shell experience for phones/tablets (≤ 768px): a fixed bottom
   tab bar, a slim sticky top bar, and five focused "views" that the JS layer
   organises the EXISTING sections into. Every feature is preserved — nothing is
   removed, only re-homed so the user sees one calm thing at a time (progressive
   disclosure) instead of an endless desktop stack.

   PSYCHOLOGY / UX PRINCIPLES BAKED IN
     • Thumb-zone first   — primary navigation lives at the BOTTOM where thumbs
                            reach, not the top (Bloomberg / Robinhood / X pattern).
     • One job per screen — each tab answers one question, lowering cognitive load.
     • News leads         — the app opens on the News tab (the hook), as requested.
     • Calm motion        — 220ms ease view-swaps, no jarring jumps; respects
                            prefers-reduced-motion.
     • Safe areas         — honours iOS notch / home-indicator insets.
     • Zero desktop bleed — every rule is inside @media (max-width:768px) or under
                            html.fnrp-mapp; desktop (≥769px) is 100% untouched.

   REVERSIBILITY
   Purely additive. To roll back, delete the two enqueue lines for
   'fnrp-mobile-app' in findex-news-runtime-pro.php. Nothing in frontend.css/js
   or the older fnrp-mobile.css is modified.
   ═══════════════════════════════════════════════════════════════════════════ */

/* The JS adds html.fnrp-mapp only when it actually mounts the shell (≤768px and
   the root exists). All structural rules are gated on BOTH that class AND the
   media query, so a stale class can never affect desktop. */
