    /* ============================================================
       Mobile Calendar - prevent Saturday column overflow
       ============================================================
       Root cause analysis (375px iPhone viewport):
       - .unb-panel padding: 32px (16px each side on mobile)
       - WordPress theme may add body/container padding: ~16-32px
       - Available width for calendar grid: ~295-327px
       - With aspect-ratio:1, cells need min ~42px (label text)
       - 7 cells × 42px + 6 gaps × 4px = 318px > available
       - Combined with border (2px×2) and padding, causes overflow
       
       Fix strategy:
       1. Remove aspect-ratio on mobile (use auto height)
       2. Reduce panel side padding for calendar step only
       3. Force min-width:0 so grid items can shrink below content
       4. Constrain label text to never expand cell width
       5. Wrapper overflow-x:hidden as safety net
