/* ==========================================================================
   calculator.css
   Design-system addon for the Home Improvement Calculators module.
   Loaded AFTER your site's style.css — every rule here uses your existing
   CSS variables (--primary-color, --accent-color, --text-main, --bg-light,
   --shadow-sm/md, --font-heading/body) so it inherits your palette and
   typography automatically. Classes are prefixed "calc-" (and functional
   hooks like ".type-section" are new, unique names) specifically to avoid
   colliding with same-named rules elsewhere in your theme — e.g. your
   theme's ".accordion-header" is deliberately mobile-only (display:none by
   default), which is wrong for an always-visible FAQ, so the FAQ below uses
   its own ".calc-faq-*" classes instead of reusing that one.
