Code/Demo/DemoHintCard.razor.scss
// Demo hint card. Same visual language as the tweak panel: 3 grouped font sizes (13 / 11 / 10), no
// letter-spacing, borders via border-width + border-color only (never border-style, which aborts the
// whole stylesheet), no blurred box-shadow on rounded elements. Root is pointer-events:none so only the
// card takes clicks. Every text colour sits above the contrast floor: instructions are never dim gray.
//
// The close control is a 42px square, matching the tweak panel. No ESC badge anywhere.
