/*
 * eu-cbam-checker.css - styles for eu-cbam-checker.php only.
 *
 * Look: a compact "tool" interface (tight spacing, small clear labels, bold result headline).
 * Colours: the site palette from style.css and design-system.css (--blue, --yellow, --grey, --light, --text, --white)
 * plus two very light tints (blue and yellow) for information and warning bands.
 * Flat colours, Arial, no gradients, no animations - same feel as the rest of the site.
 *
 * v37 (chat 12g): the two boxes are Cards (white, 3px yellow top line, 24px padding), inputs 46px high with a
 * 1px #767676 border, labels 1rem bold, help text 14px #595959, info band = Info box.
 *
 * Layout: two columns (inputs left, assessment right). Below 800px they stack.
 * Everything has min-width: 0 so nothing forces a sideways scroll, down to 320px wide.
 *
 * Contents: setup / breadcrumb and title / two columns / form fields / code search /
 *           tick boxes and radios / buttons / assessment panel / key-value tables /
 *           question that needs attention / bottom band and notes / small screens
