/* ============================================
   BOTTOM BAR v9.2 — Horizontal Expand Tabs
   
   WHAT CHANGED vs v8.4:
   - Layout: horizontal (icon + text side by side)
   - Inactive tabs: icon only (text hidden)
   - Active tab: pill expands, text appears beside icon
   - Animation: max-width + opacity (GPU-friendly)
   - Press: scale(0.93) with bounce-back
   - NO backdrop-filter (60 FPS guaranteed)
   
   COLORS: DATOUR dark neutral + subtle violet pill

/* Issue 1 fix: hide the global bottom-bar on the booking screen.
 * The booking form's last field (remarks) sits under the fixed bottom-bar
 * (position:fixed, z-index:1000), so tap-to-focus lands on the bar instead of
 * the textarea — programmatic .focus() works only because it scrolls the field
 * into view. Hiding the bar here also matches checkout-flow UX: users should
 * complete the booking, not navigate away mid-form. */
