Adaptive Shell

Description

DeepSeek Harness plugin: adapts to phones, tablets, and desktops based on screen size and aspect ratio. Adds safe-area insets (notches and Home indicators) to input fields and conversation headers, tightens spacing on narrow screens, enlarges controls on touch devices, and switches the color scheme to the Miracle design language (warm-white paper, ink-blue tones, blue-violet branding, softly rounded corners, restrained shadows, with a separate dark-mode palette). On phones, the 56px icon bar is fully collapsed (access is in the conversation header); the sidebar and main conversation move in sync according to Miracle motion guidelines (transform only, both directions finish together, instant fallback with reduced-motion); it does not alter document height or include any overlays, so it cannot lock the interface; no desktop-sized window rules are triggered.
