 * Design tokens (colors, fonts, spacing) live in theme.json.
 * This stylesheet handles:
 *  - Section-specific layouts (each `.t4lus-*` class is the source of truth
 *    for one visual zone, so we don't fight the block editor's inline styles)
 *  - Custom animations (marquees, glitch, pulse)
 *  - Effects (grid overlay, watermarks)
