/// Loads a .loading file (tiny UI-only binary), renders the screen,
/// and provides progress updates during the main splashpack load.

/// Strategy:
/// 1. Blank the screen immediately (user sees black, not frozen frame).
/// 2. Load the .loading file (small, fast).
/// 3. Upload texture atlases, CLUTs, and custom font textures to VRAM.
/// 4. Render ALL elements to BOTH framebuffers using direct GPU commands:
/// - Images via sendPrimitive(GouraudTexturedTriangle)
/// - Custom font text via sendPrimitive(TPage) + sendPrimitive(Sprite)
/// - System font text via font.print()
/// - Boxes and progress bars via sendPrimitive(Rectangle)
/// 5. FREE all loaded data (loader pack) so the splashpack has room.
/// 6. During splashpack loading, call updateProgress() to redraw ONLY the
/// progress bar (simple rectangles in both framebuffers — no VRAM needed).
///
/// The progress bar is found by looking for a PSXUIProgressBar element named "loading".
