/* ============================================================================
   We Switch Payroll free tools — shared design system.

   Extracted when the hub went from 2 pages to 7: the same ~90 lines of tokens,
   layout and component CSS had been copied into every page, which is how seven
   calculators drift into looking like seven different products. Page-specific
   rules stay in a small inline <style> on the page that needs them.

   Cached for an hour by _headers, so the 2nd..7th calculator a visitor opens
   costs no CSS at all.
