/* ============================================================================
 * components.css — Card and panel styles for the individual sections.
 *
 * Everything here is hover state that used to be React state. Each card
 * previously tracked `hovered` in useState and recomputed a dozen inline
 * style objects on mouse enter and leave; the browser does the same job for
 * free with :hover, with no render pass at all.
 *
 * Accent colours are passed in as the --accent custom property, then blended
 * with color-mix() where a translucent tint is needed. The old code built
 * these by string concatenation (`accent + '55'`), which produced invalid
 * values like "var(--blue)55" — so the tinted borders, shadows and cursor
 * spotlight never actually rendered. They work now.
