/* Calculators — shared panel/table styles plus the calculator page shell. */
/* Shared visual language for the six calculators on /tools. Plain, unscoped
   CSS on purpose — like quiz.css, but for the calculator panels.
   Each calculator component imports this file directly, so the form fields,
   result tiles, table, chart, and budget-bar styles stay consistent without
   duplicating the same rules across six separate scoped <style> blocks. */
