   PROVIDENT FUND (PF) CALCULATOR - TOOL APP CSS  (TOOL HALF)
   Upload to: /wp-content/uploads/2024/02/salarycalculator/providentfund/providentfundtool.css
   Prefix: pf- (provident-fund-calculator, registered in
   SALARY-CALCULATORS-SILO.txt s.9d)
   Loads BEFORE providentfund.css. Never merge the two files.

   COPIED, NOT AUTHORED. Derived from the live post-tax-salary tool
   stylesheet posttaxtool.css, fetched 23 Aug 2026, with every ptsc-
   string renamed to pf- and no rule edited. It carries the silo INPUT
   FIELD RULES unchanged: 44px left padding on any input with a prefix
   icon, icon at left 14px, and native number spinners hidden.

   Zero class overlap with providentfund.css. This file owns the hero
   and the calculator; that file owns the ten SEO widgets.
   Anything genuinely new sits in the ADDITIONS ONLY block at the end.
