/* ==========================================================================
   SPACE THEME — inspired by the attached Lively Wallpaper HUD
   (pure-black cosmos, twinkling particle starfield, film grain,
   Doto HUD typography — all white on black).
   --------------------------------------------------------------------------
   This file layers OVER css/styles.css. Layout and class names are untouched;
   only palette, typography accents, and background layers change.
   The starfield itself is injected by js/space.js as:
     <div class="space-bg"><div class="particle-field">…spans…</div></div>
