   INTERNSHIP STIPEND CALCULATOR - TOOL APP CSS (TOOL HALF)
   Upload to: /wp-content/uploads/2024/02/salarycalculator/internshipstipend/internshipstipendtool.css
   Prefix: isc- (internship-stipend-calculator)
   Site Design System: Dark #0A0F1C | Green Silo #10B981
   Font: DM Sans
   Loads BEFORE internshipstipend.css. Never merge the two.
   REBUILD 27 Aug 2026: four-file split, migrating off the legacy
   single-file shape. Input left padding raised 42px to 44px per
   the silo input field rules (44px is the floor, not the target).
