- Add prepare_global_blur() method combining Deep Sea render + blur - Add fb_scale parameter to setup_fbos() for high-DPI display support - FBOs now created at scaled resolution (width * fb_scale, height * fb_scale) - prepare_global_blur() auto-initializes FBOs if scale changes - Add test_blur_pipeline_prepare_global_blur - Add test_blur_pipeline_high_dpi_scaling Task: Phase 2, Tasks 1-2 of frosted_glass_20260313 track
