/* ============================================================
   UOES Tools — shared chrome for the calculator-style pages
   ------------------------------------------------------------
   Used by workload_estimator.html and credit_hour_planner.html.
   Both are wide, multi-column tools built from the same parts:
   a centred header, red section headings, white cards holding
   number/select fields, a results block of stat tiles and a
   breakdown table, and a print view that shows only the report.

   Load order: base.css -> calculator.css -> <page>.css
   Anything the two pages do differently lives in the page file.
