lullogram: sleep & calm tools

choose your look — when you first open lullogram you now pick how it feels: system, auto, dark or light. a little live preview shifts as you tap so you can see it before you commit. auto follows your local sunrise and sunset, so the app warms up in the morning and settles down after dark on its own. change it anytime in settings. try before you decide — pro soundscapes, exercises, fidget toys and routines now come with three free goes each. tap one and you get a small card first: try it now, or take a look at pro. no surprise paywall in the middle of a calm moment. the full upgrade only steps in once your free goes are used up. quieter sleep nudges — the "add last night's sleep" prompt now shows once a day at most, and stays gone for the rest of the day once you wave it off. it also waits its turn instead of jumping in front of a soundscape or a tool you opened from a widget. and the usual round of small fixes to keep everything steady and calm.
