Stoic Feeling Slider

In this onboarding or daily check-in screen, the user interacts with a minimalist slider to log their current mood. Dragging the slider thumb dynamically changes the header text from 'How are you feeling' to 'I'm feeling' followed by a descriptive mood label (e.g., 'Not great', 'Good', 'Great'). The text labels transition with a swift, elegant crossfade and subtle vertical shift, matching the direction of the slider's movement. The slider track itself fills with a solid black color, providing clear visual feedback of the selected intensity.
