/* ═══════════════════════════════════════════════════════════════
   SITE LOADER — first-paint loading screen shown on initial site
   load AND reused by PageLoader.vue for per-view data fetches.
   Design language matches the landing hero: light-blue gradient,
   giant "10x" watermark, gradient wordmark typewriter animation,
   gradient progress bar anchored at the top of the viewport.
   Apple-inspired: clean, spacious, intentional motion.
