/* Minimal custom CSS — most styling comes from Tailwind via CDN.
 *
 * NOTE on the dark theme: Tailwind 2.x's color palette only goes to
 * gray-900 — `bg-gray-950` (used in the body's class attribute) is a
 * 3.x-only class and resolves to no rule, leaving the page on a
 * default white background. The explicit body rule below establishes
 * the dark surface without depending on a specific Tailwind version. */
