    /**
     * Optional background color for header rows. Because the table uses Shadow DOM,
     * host applications cannot easily override the internal header row background.
     * Setting this property (only meaningful when the row is inside a <cds-table-head>)
     * will apply an inline CSS custom property that the styles consume.
     *
     * IMPORTANT: For theme compatibility, use the CSS light-dark() function:
     * - Recommended: headerbackground="light-dark(#f0f0f0, #404040)"
     * - Avoid: headerbackground="#f0f0f0" (only works in light theme)
     *
     * Accepts any valid CSS color value including:
     * - CSS light-dark() function: "light-dark(#ffffff, #333333)"
     * - CSS custom properties: "var(--my-header-bg-color)"
     * - Static colors: "rgb(229,229,234)" or "#e5e5ea" (not theme-aware)
     *
     * Example: <cds-table-row headerborder headerbackground="light-dark(rgb(229,229,234), rgb(80,80,85))">…
