/*
 * KinetiBloom landing page.
 *
 * Dark-first and deliberately committed to one look, the way a game site is
 * rather than the way a document is. Original styling; no framework, no web
 * fonts, no external requests of any kind.
 *
 * Accessibility is not traded away for atmosphere:
 *   - Body and heading text clear WCAG AA against their actual backgrounds.
 *   - Every animation is gated behind prefers-reduced-motion.
 *   - Focus is always visible, on a colour that reads against the dark ground.
 *   - prefers-contrast: more swaps in flat high-contrast surfaces.
