   PC DESKTOP LOADING SCREEN
   The brush-drawn ensō is the progress indicator: main.js draws it as resources
   load. The theme kanji (希望 HOPE / 虚空 VOID) ink in, ink motes and petals
   (canvas #pc-loader-ink) gather into the circle, a vermilion seal is stamped on
   completion, and the exit opens like a portal through the ensō. Hidden on mobile.
