/* ============================================================================
   calc.css — shared look for the 61 free calculators.
   Loaded LAST in <head> (site_sync.py "calc-head" region), so it out-ranks each
   page's own inline <style>. The pages come from three template generations
   (old-gen <header>, new-gen .page-header, page-wrap); this sheet makes them
   read as one product. Selectors are `body.aim …` so they beat the pages'
   `.aim …` rules by one element of specificity — never use !important here
   unless a page's own rule already does.
