SettingsModal + ArtworkGenerationModal: - Backdrop: bg-black/60 → bg-black/80 (darker, less bleed-through) - Backdrop blur: backdrop-blur-sm → backdrop-blur-md (stronger blur effect) - Modal surface: added lyria-surface color (#1a1a24) to tailwind config for solid, opaque modal backgrounds Result: Background elements are much less visible behind modals, improving readability and focus.
