dsh-maestro-mobile

The DeepSeek Harness Web UI was designed for desktop viewports. Once the window shrinks to a phone or tablet, the sidebar squeezes the main pane, settings and preview dialogs overflow the screen, and composer widgets such as the permission capsule and model switcher start overlapping. dsh-maestro-mobile plugs exactly that gap: below 1024px it converts the sidebar into an approximately 80vw left overlay drawer, turns the settings, explorer, and preview panels into bottom sheets with safe-area-inset handling, and fixes status-bar padding and double-tap zoom. At 1024px and above the plugin is a complete no-op, so the desktop experience is left entirely untouched.

Architecturally the plugin uses a deliberate host/client split. The host-side apply() is intentionally empty; all browser behaviour lives in the client layer, driven by a single zero-dependency MutationObserver reconciler that concatenates base, layout, compat, and misc stylesheets into one injected tag. Every mobile rule matches only the max-width: 1023px breakpoint, and tablet (768-1023px) versus phone geometries are verified independently. Appending a debug query parameter to the URL summons a floating status bar that displays viewport dimensions, framework version, floating-panel state, and JS errors in real time for on-the-spot diagnostics.

It is built for developers and power users who open DSH Web on a phone, a tablet, or any small-screen device without wanting to fork the core source or alter the desktop layout. After a single install and one web-process restart, the same DSH interface offers drawer navigation, bottom sheets, and notch-safe padding on a handheld, while the 1440px monitor at the desk remains completely unchanged.
