We never rely on `prefers-color-scheme` directly inside the * stylesheet for color values; instead, the inline script reads * localStorage / matchMedia and sets data-theme synchronously, so there * is no flash-of-incorrect-theme. * - All component CSS uses semantic tokens (--color-text, --color-surface, * --color-mark-bg, ...) and never hardcodes hex values, so the dark * theme picks up the new tokens automatically. * ============================================================ */ :root, :root[data-theme="light"] { /* Base canvas */ --color-bg: #f7f8fa;
