+**Core Web Vitals:**
+- LCP (Largest Contentful Paint): < 2.5s
+- CLS (Cumulative Layout Shift): < 0.10
+- TTFB (Time to First Byte): < 600ms

 **Behavior:**
-- Preloads critical CSS/SVG assets
+- Adds `role="status"` and `aria-live="polite"` to preloader container
+- Preloads critical CSS/SVG assets via `fetch()` with `cache:'force-cache'`
 - Shows LCARS-style boot bar with `role="progressbar"`
-- Respects `prefers-reduced-motion` (simplified indicator)
+- Respects `prefers-reduced-motion` (100ms shortcut to completion)
 - Updates `aria-valuenow` as resources load
-- Hides and dispatches `CustomEvent('preloader:done')` on completion
+- Sets `aria-hidden="true"` and hides preloader on completion
+- Dispatches `CustomEvent('preloader:done')` when finished
 
 **Accessible Features:**
 - ARIA progressbar with live value updates
+- `role="status"` and `aria-live="polite"` for screen reader announcements
 - Visual boot animation (LCARS style)
-- Status text for screen readers
-- Reduced motion support
+- Reduced motion support with fast completion

 **Behavior:**
 - Manages background SVG/CSS layers per theme
-- Star Wars: HUD grid overlay with animated scanning line
+- Star Wars: HUD grid overlay with animated scanning line (2s linear animation)
 - Cyberpunk: Neon noise overlay with shift animation
 - LCARS: Minimal/none (clean interface)
 - Applies gentle pointer parallax after preloader (disabled for reduced-motion)

+- Activates theme-specific animations:
+  - LCARS: 1.6s cubic-bezier(.2,.9,.2,1) transitions
+  - Star Wars: 1.8s ease-in-out with HUD class activation
+  - Cyberpunk: 1.2s steps(6,end) with 'glitch' class
+- Sets loader-sample `.bar` width to 100% and adds 'active' class on preloader:done
