/* Boot splash — true-black canvas so there is no white flash before Flutter
   paints its first frame. Moved out of index.html by D1-03: an inline <style>
   would force 'unsafe-inline' into style-src... which the Flutter engine needs
   anyway (it injects styles at runtime), but keeping the document itself clean
   means the CSP can be tightened the day the engine stops doing that. */
