/* calculator.realestate design system: COMPONENTS (TD-214 B2 r1, concept A "Keypad").
   Uses only tokens from ../tokens/tokens.css. Every rule uses LOGICAL properties (inline/block, start/end), so a page
   with dir="rtl" (Hebrew) mirrors without extra rules. Every control is at least --target-min (44px) in both
   directions (WCAG 2.2 2.5.8 needs 24px). Every interactive element shows a focus ring of --focus-w in --c-focus. */
