/* The loading screen: the ViktoPay mark, a light passing across it, and a
   thin line that runs under it. Served as a file (the CSP allows no inline
   <style>) and linked from index.html, so it shows on the very first paint,
   before the application's script has arrived; React replaces it when it
   renders, and the session splash reuses the same classes. */
