/* ═══════════════════════════════════════════════════════════
   [FIX] Mobile GPU Layer Consolidation — REVERTED 2026-06-18
   Forcing `translateZ(0)` on `.topup-main` did the OPPOSITE of consolidating:
   `.topup-main` is the full-height scrolling column (far taller than the
   viewport), so promoting it allocates one enormous backing store that
   exhausts the mobile GPU's texture memory → the garbled pixel bands seen
   across the package grid and Payment Method section on Android Chrome.
   Let the column paint/tile normally — do NOT force-promote tall elements.
   See .claude/COMMON_MISTAKES.md §7.
