/* ============================================================================
   FINDOMBOOK - LUX THEME (cyberpunk / holographic)
   File: /var/www/html/theme_lux.css
   Loaded AFTER feed_style.css so it overrides the palette and the effects.

   Design goals
     * neon that pulses from BLUE to PURPLE
     * holographic, semi transparent, "3D" cards with a mouse-over sheen
     * READABILITY FIRST on the small FindomPhone MOAP screen (about 500x700):
       under 900px we switch to a single column, bigger text, no blur (blur is
       expensive in the SL viewer), bigger tap targets.

   Performance notes (important for MOAP):
     * only transforms / opacity / background-position are animated (GPU cheap)
     * backdrop-filter is used on desktop only and disabled on small screens
     * every animation can be switched off with prefers-reduced-motion
   ========================================================================== */
