 *               landing page (warm-white background, serif headings).
 *  - gray-*   → cooler neutrals used in the admin dashboard and auth
 *               screens (white background, system-font UI).
 *
 * Both palettes share the same scale (50–900) so they stay visually
 * consistent while giving each context its own temperature.
