/*
 * FieldView — Liquid Glass (custom stylesheet, no external library)
 *
 * This single file replaces Tailwind CDN. It covers:
 *   1. A CSS reset/preflight
 *   2. Design tokens (color scale + glass + shadow + radius + type + motion)
 *   3. Ambient liquid-glass page background
 *   4. Every utility class the app actually uses (bg-*, text-*, p-*, flex, grid, …)
 *   5. Responsive (md:, sm:, lg:) and pseudo-class (hover:, focus:, peer-checked:, group-hover:) variants
 *   6. Component classes used by the PHP pages (hero-bg, cta-btn, gradient-text, feature-card, fade-in, spinner, upload-area, badge-*)
 *
 * Design direction: Apple-flavoured "Liquid Glass" — vivid ambient background,
 * frosted translucent surfaces, soft layered shadows, colourful tinted panels,
 * generous corner radii, subtle motion.
