     .ptsc-result CSS: display:none  JS: 'block'(show) / 'none'(hide)
     #ptsc-rebate-row CSS: display:flex  JS: always sets 'flex' (never hides)

   JS-CREATED <tr> CLASSES (via tr.className):
     'ptsc-slab-zero'    inactive slabs (salary below slab min)
     'ptsc-slab-active'  active slabs where tax > 0
     (no class)          active slab where tax = 0 (0% first slab)

   CSS-ONLY CLASSES (in HTML, never touched by JS):
     .ptsc-input-group      input row wrapper
     .ptsc-hint             aria-describedby hint span
     .ptsc-result-header    header div inside result
